One thread on buffing the champion. One on nerfing GWM.
I'm getting mixed messages.
Nothing contradictory about it. The Champion's improved crit range is it's main claim to DPR fame, and crits only multiply damage dice - a Champion using GWM has no particular edge in exploiting that feat compared to any other fighter (or barbarian or paladin or whatever) doing so.
But, at the same time, GWM does represent a high-power DPR build, and relative to full casters and the like, the Champion, along with other melee types could be 'hurt' by nerfing it. Thus it might make more sense to address a perceived balance issue with GWM by buffing up other melee options (combat styles) to rival it, instead.
I am here to convince people like you that the feat needs fixin': catching attempts at derailing the analysis, pointing out bad arguments and catching simplified calculations.
I am here to convince people like you that not everyone thinks the feat needs fixin': in spite of your repeated claims that present your opinion as a universal fact.
Hm...
So, we do know exactly how the GWM feat works, and the -5/+10 portion of it which seems to be what everyone's hung up on, is easily analyzed for it's affect on DPR. So the 'universal' fact is not in dispute, just the opinion of whether that effect is too much (or tool little, or Goldilocks 'just-right'), and whether a given DM wants to change that.
But the actual OP's topic wasn't whether it was broken or should be fixed, but how to fix it.
Disadvantage would make the feat more powerful:
That was how it seemed to me on the surface...
>=5:
Disadvantage --> 64%
-5 --> 55%
Normal --> 80%
Advantage-5 --> 79.75%
>=10
Disadvantage --> 30.25%
-5 --> 30%
Normal --> 55%
Advantage-5 --> 51%
>=15, 15 max using the -5
Disadvantage --> 9%
-5 --> 5%
Normal --> 30%
Advantage-5 --> 9.75%
So, the first line of each group is the natural roll you need to hit before applying the GWM penalty/disad? And, the 'Normal' line is the % chance to hit w/o applying the penalty /and/ also the chance to hit when the disadvantage version is countered by Advantage? Correct?
