There's a distinction between over and underpowered and broken. The fact that many people get it wrong does not change that. Broken means, well, broken. Unplayable. Not usable in its current state. Game destroying. Something can be overpowered or underpowered yet not break anything.
Whitey, you and I seem to agree on a lot of things, and I respect you for that. However, here I have to stand opposed. The common use of a word, whether technically correct or not, still counts for something.
If 90% of the people understand the word "download" to mean "copying a file from a remote server to my local computer," and "upload" to be the opposite, then the fact that the original definitions of these words were the reverse is of little consequence. This is what people mean, and trying to use the words "correctly" is only going to generate confusion among the masses. Bully for you if you know the truth, but it's not going to change how people talk.
Likewise, easily over 90% of gamers here and abroad the internet use the term "broken" to mean "overpowered" (and perhaps occasionally "underpowered," but usually the former.) In fact, they often use the term to refer to a perceived imbalance when there may in fact not even be an actual imbalance in practice.
I'm sure they would use "broken" in a case where the game became literally unplayable, but that is not a prerequisite in common parlance. The way the majority of people use the word "broken" in the context of gaming is highly subjective, to the point where I don't really think any one definition can be universally applied. You know what they mean, let's just leave it at that.
I was purposefully pointing out the distinction to make my stance more clear. I needed to express gradations to ensure that while I will give that the card may be slightly on the overpowered side for an act 1 item, even given its restrictions, I do not find the card game breaking. I did it because if I use the word broken the same way others commonly do, then I no longer have a term to describe something that breaks the game, so I was making the distinction in order to better express myself, not particularly to insist that they are wrong to use it the way they were. I may have not been as clear as I wanted to, so for that I apologize.
