Any worry about "perfect balance" is worthless in the first place because this has never been a perfectly balanced system to begin with.
Any degree of intimate knowledge of the system can help an experienced player to break encounters in countless ways, and sometime breaking things is precisely part of the fun.
So when people act as worrywarts about how a change could "compromise the current balance" in a game that is still one year away from release and incredibly far away from being finalized in most of its aspects, they deserve to be mocked for it.
