Except it didn't work exactly like that. Let's take SCH's ability Energy Drain for example:
Devs showed the ability being removed in the pre-patch, healers universally said this was a BAD idea because at the time SCH's mana regeneration was tied to Energy Drain not Aetherflow like it is now.
Devs refused to budge, Energy Drain was removed, lo and behold exactly what we said happened and the Devs were forced to give it back (not even mentioning SCH had no Aetherflow dump after the change so we just fired off useless heals).
Stuff exactly like that is why the devs stopped giving out detailed changed pre-patch notes.
But then they dropped bombshells and basically said "deal with it" which made the players even more angry because we felt our feedback was meaningless and job balance was terrible.
So then they had to backtrack AGAIN.
