Game balance is important, casual or not. It is about improving the game experience for both players, which can't be a bad thing nonetheless, and trying to push forwards to it shouldn't be discouraged by laid back attitudes in my opinion.
And GW community is very different to the Xwing, specially since GW basically cares nothing about competitive gaming, neither worries about having FAQs in time, or consistent rules (skyfire and nobody has it, genius).
