This thread feels a little close to edition warring: complaining without offering constructive criticism or useful feedback.
I think it is too limiting to require all complaints to have an accompanying solution or even work toward one.
That said, imbalance isn't an issue, IMO, for most rules sets. I've seen too many that wind up squeezing the freeform nature from RPGs in an effort to impose balance. In the end, a GM steers toward the balance at any given game table and the gathered RPGers play within that framework or even push the envelope a bit. A more balanced ruleset can become imbalanced while a very loose set of rules can seem perfectly fine during play. It's up to the designers to give good advice in a GM's Guide as to how important balance might be and help a GM decide what needs emphasis with an individual group.
