Transfiguring Roar
Arcane
My point is that he might do better to try and remember what made playing RPG's fun when he first played them. I am guessing it was not how balanced or elegant some system was, but rather something else. I think he may be over thinking the design and that something less obsessed over might in fact be more fun.
I agree with what you're saying, but I personally find the problem is how the system holds up long term, after the initial and/or mid-term fun. That's when some semblance of balance and challenge becomes a little more important and fun to me in tactical games.
Edit: I guess end-game balance is what matters to me.
