•WoW is as perfect as it can be of your own preference
•Can't detect PvP-PvE differences, because let's say Battle Fatigue affects the whole game, but from PvP PoV it's still the equal change.
•No knowledge of, if abilities had different values before,because say you haven't played the game,just trying it now.
I'm telling you that this perfect game has Battle Fatigue in it.
Can always divide all healing by 1 - , and point finger on the result numbers that those were the original values.
Refute that there could've been Battle Fatigue in the game.
The task is not possible.
If the perfect game could've been achieved via Battle Fatigue, then suggesting that BF is always, in any circumstances a bad change is plain false.This is also the case for any other general change, such as Resilience for example.
So every complaint that would always be true about BF, like 'it affects classes differently' or 'lazy change' can not mean barrier to its necessity/application, because they would suggest BF is always a bad change, which is false. Some of similar concerns may tighten the temporary % change, but by no means deny application.
Consequently, any considerable legitimate concern that is raised against the application of BF must not be an always present concern. So if the concern could always be told about the nature of BF, the concern is inappropriate to deny application.
The idea is not that overnight put 50% Battle Fatigue on to Live servers. Yes, BF does require additional changes after application, since it affects classes differently. But for example gradually increasing BF needs much less adjustments, all the while PvP is getting fixed in general, the benefits are massive.
During longer testing periods, for example a beta, the testing environment is given for even considerably larger amount of needed adjustments after possibly higher BF % application.
To be very concise, general issues ought to be solved not solely, but by the aid of general changes, such as generally high burst/CC.
Note: The game has to have healing in it, and the alleged Battle Fatigue is 0%< Battle Fatigue <100%.
