Here's my only issue. In a pen and paper rpg, or even in a console rpg, the choices I make would likely be permanent. They may not be changeable until deep into the game, if at all. I may need to start an entire new playthrough to swap that choice I made in the first 10 minutes(I'm looking at you console JRPGs, lol).
However, those choices are defined.
In WoW, the "choices" are moving targets, and will be redefined as soon as a hotfix can be implemented. Naturally, my "choice" will always be the most OP option, and thus subjected to likely the quickest and most severe redefinitions, aka a nerf.
With the ever-changing state of the game, I am not really making a choice, just a guess. An RPG is about meaningful choices, not about a guessing game, so that's my only issue with it.
If they have the courage to make us make a choice, then also have the courage to make one of those choices wrong. I'd like to see them not rebalance them, just leave the meta the meta. Then, I think the complaining would be coming from the other side of this argument.
