how did fiora pop off?
fiora builds lifesteal, aside from black cleaver, she builds ravenous hydra which got more AD, bloodthirster which got more AD and, and the big one- death's dance which got it's dmg to dot conversion passive doubled, and again, more AD, all of which means more true damage
still needs to be nerfed of course, but it's fun to about how seemingly slight number changes in the system can completely bust a champion
or maybe it's something else?
