1. Is it correct that good factions get 2 resource, 1 diplomat and 2 defensive development tokens whilst evil factions get 2 resource, 1 training ground (tactic card) and 2 defensice tokens? If so, is this becase evil factions would rather attack (using tactic cards) and good factions use diplomacy (in general, just to give the game 'flavour and diversity', I do nderstand that good factions could quite as easily spend their time attacking and vice versa for evil factions!!!)
I hadn't noticed that disparity before, but I'm sure it's on purpose. Developments have relatively little impact on the flow of the game in my experience, so I wouldn't think this subtle variety would greatly impact the "Good" factions' ability to attack, nor the "Evil" factions' ability to use influence. it certainly hasn't in our games.
2. During your turn (or battle in which you are defending - as this is not your turn) how many tactic cards can you use at any one time? If you have multiple copies of a card can you use them all at the same time (rally for example).
It's my understanding that you can use as many tactic cards as you want so long as the playing conditions are valid. You wouldn't be able to use a card that's played "on your turn" during a defensive battle because it's not your turn, but most tactics that are relevant to a battle are played "during a battle" anyway. Also, remember that you can't play tactic cards you just drew this turn (on that turn.) As far as I know you can play multiple copies of a given card if you have them.
