It is about having Blow, the chain skill, more often. Is the lower damage of the first one worth having it every 30s as opposed to every 40s? Would you rather have a skill that deals about 6.400 on a 30s CD or 8.400 on a 40s CD? I tend to think it's the 40s one, but I don't feel that's absolutely clear.
Without reading your detailed reply with all those charts, I wanna say that after a simple math it looks like if the fight lasts longer than 5m, the 30s one will deal more dmg ![]()
in a 5m fight, the 30s can be used 10 times, so 10x6.400 = 64k, while the 40s can be used 7.5 times which is 63k, but since you cannot use it 0.5 times haha, it will be 58.800
So imo, in fights that lasts less than 5m, the higher dmg one might come with higher dmg output without taking crit into consideration ![]()
