Let's say a guy plays ADC top and takes fervour keystone mastery
He stacks his fervour passive and plays agressive (he autoattacks very rarely the creeps - to lasthit or to maintain fervour (lasts 5 sec) so that the lane freezes and he can zone his opponent out) With the base AD buffs + fervour stacked, he now has +15 AD at lvl 1? Has anyone faced that in PBE? It seems just like impossible to win.
