I won’t call this an AGOT or RS. Looks similar, yes. 
Compared to both, it’s a lighter version in terms of complexity and components. Not necessary a bad thing.
I think TI4 is a great game, but the game is still too long and cumbersome for my liking. This and the new civ game fits well to my appetite and game time.

The art of controlling how much fate to spend and how much to save for the future is hard to grasp in this game. It’s a big departure from other mainstream ccg where having your killer combo out doesn’t neccesarily win u the game.
Most who don’t get it finds it more comforting to attribute it to luck. 

How many part time hour does it take to buy a single expansion pack? 
If that's an issue, I think you have bigger problem to think about rather than FFG's business decision.
My next point being, marketing a product to everyone seems logical. But a key aspect of making a business decision is which consumer group to focus on and which to give up. For someone in serious financial crisis or gets passed over thus, I don't think that's going to be my key customer group. I'll be more interested in keeping my key group happy.
I for one am glad a larger card pool is out before Christmas to keep my interest rather than letting it decay. If all their future cycles are as such, then yes I think FFG is playing with the fire ring. If the intention is as per how I speculate, good job. 
For now I choose to trust them. 

If he leaves star war to focus on l5r, I would say good? 

I think the bottom line here is this:
Stale metas kill the game. Imperial in 6 weeks ensures that won't happen.
Second, people are acting like your 3 core set decks are going to be garbage. Not so! Core set cards tend to be purposely strong to ensure people buy 3 of them. 
Even after the whole Imperial cycle is out 3 core decks will still be good. You're just not going to have the variety of good builds and there may be an upgrade or two that you miss out on. 
Still, if you play well you're going to do fine. Buy the packs you like when you can, your decks are not going to suddenly be obsolete in two months, it will take longer than that for the meta to figure out what to do with the new cards anyway.

Get out, this is L5R, not Game of Thrones.  You have your own forums.

Better make a thread about it so FFG knows they have to change the rules for you.
Or better yet - take this one 

Too many people can’t seems to manage uncertainty/probability and yet blame it on something else

Yup... I definite do not make bad play. My wins were all skilled play, losses were all because of:
-bad luck on my
-opponent gets lucky draw
-opponent abuses bad mechanics

Or the mechanic is broken.
Definitely not because I made bad plays.

My final effort to be rational with you:
Costs aren't just things printed on a card.  There are many different kinds of costs.  Perhaps you should take an economics class to learn about such things.  In terms of the game, costs are what you pay to try and achieve a particular goal.  Individual cards themselves have costs, which you pay, like the Fate cost, or the honor cost on Assassination.  However, you also pay the opportunity cost of not having that card available to use later.  Perhaps it would have been better used later, not now?  Other opportunity costs are choices you didn't make. 
For example, You can only afford one more character, and have two choices.  A cost you pay is not buying the other.  Finally, there are a ton of other choices in choosing your conflicts.  For example, if you commit Dude X to defend, you don't have him to attack.  If you commit Dude Y to attack, you don't have him to defend.  If you choose the Ring of Fire with No Fate on your first attack, then your opponent has the chance to choose the Ring of Air with 2 fate on their first conflict, costing you that fate (Even on top of that choice maybe mattering, as perhaps you are at 1 honor).  
So in your choice of results from dueling, you need to either choose your duel in situations where you will ALWAYS get the result you want, IE bully dueling (Dueling from such a high skill your opponent can't win, so doesn't try), or you need to use your duels in situations where you feel like the result will get you what you want, even if it costs you something else.  If you had a card that said "While in a conflict where you have 3 participating Characters, your opponent has 2 participating character, and you are losing, Bow a character with more Military skill than one of your opponent's characters -  Steal 4 honor from your opponent" Would you play it?  That is the sort of specific situations where dueling is good.  What if the ability was all the same, except the result was: "Your opponent chooses to Give you 4 honor or bow his character"?  That is basically all a duel is.
If you don't like the word "Cost" choose a different word, but the concept is ESSENTIAL to any sophisticated strategy game.  
And on your point of "Its too powerful!"  That is because you are choosing your costs poorly.  Don't choose duels where you have to bid 5 and potentially lose 4 honor.  Bad play doesn't make rules broken.  What you are describing is basically bad play.  In Chess, you don't intentionally move your Queen where it is easily captured for no reason.  In MtG, you generally don't swing with your 1/1 while you have no cards in hand if your opponent has a 3/3 that they can block with.  You are basically arguing that bad choices makes the game unbalanced.  

Dueling mechanics has poker element into it. 
Op is claiming what's called an optimal play depending on two initial conditions, which would result in 2 expected outcome. Generally it is correct.
The poker element comes in where you have to play a mind game of you know that I know that you know... to change your action to result in an unexpected outcome for your opponent. 
I think that's a good mechanic that mimics the dueling of the old but with more at stake. Good improvement I would say, bad for some who doesn't know how to play the player

How many part time hour does it take to buy a single expansion pack? 
If that's an issue, I think you have bigger problem to think about rather than FFG's business decision.
My next point being, marketing a product to everyone seems logical. But a key aspect of making a business decision is which consumer group to focus on and which to give up. For someone in serious financial crisis or gets passed over thus, I don't think that's going to be my key customer group. I'll be more interested in keeping my key group happy.
I for one am glad a larger card pool is out before Christmas to keep my interest rather than letting it decay. If all their future cycles are as such, then yes I think FFG is playing with the fire ring. If the intention is as per how I speculate, good job. 
For now I choose to trust them.
