IE stacking in URF isn't fair; every other class still needs to itemize.
I'm tired of getting blown up by Twitch and co. because they can dedicate a build 100% to damage because a global aura + Runes is taking care of their other statistical needs on the back-end.
Other classes still need to itemize in Health, Resistances, and Penetration, or they will not be effective. I understand there is a concern that ADCs and other auto-attack-centric Champions can be weak in this mode, but I feel like that could be dealt with in a way that still requires them to itemize like everybody else.
There's nothing you can do against the Critical Strike Damage and Attack Speed global buff and the Infinity Edge stacking that goes along with it. You can still itemize against AP and AD Assassins with some efficacy. But what's offered by the globals to ADCs and others who make use of Critical Strike Chance/Damage, is scaling upon scaling that incidentally hyperscales Lifesteal as well, turning them into Tanks.
Does anyone agree?
