I think it says something about the state of AP that the average tank build only has one MR item
VS anywhere from 2-3 armor items. Life would be so much easier for AP if
and it's upgrades were nerfed. 70 Magic resist combined with 500 health and regen is just absurd. Not to mention the fact that both
and
are such good items that some champions might consider taking them even into an all AP comp.
As an AP champion I just despise the moment when a champion finishes their
or
because it just basically means that that champion is effectively not worth even attacking anymore except to clean up stragglers the AD champs missed.
is too good, but hitting the actual tank items is not the answer. It's good for a class to have weaknesses, as long as it also has strengths.
then yeah, you would want multiple MR items.
though. Both individually, champion by champion, and especially as a whole team comp. Non-pro players basically don't even think about "is this comp very physical heavy" until after the game when it's time to write another "nerf Rammus" thread.
