Just kind of stating, that they 'nerf' is hardly a nerf at current state and more a 'buff' of rage, because you can now buff your self or debuff the enemie, both cases are pretty broken on their own way. Instead of increasing the debuff effect, they shoud just have lowered the crit-chance buff, wich many of us suggested. Give it an increase of 50% for more than one round, not 100%.
100% critchance from Rage makes every other 'crit-chance' increase pretty pointless as many already stated.
