GP always builds carry, Fiora often builds Bruiser

Building full carry on GP has been popular since his conception, hence critplank. They basically killed off any notion of tankplank when they reworked him so his only role is high damage.

Fiora on the otherhand, she is too easily poked and the rework/item changes just made them better on her. I like BotRK and Titanic Hydra. Then again I always played her tankier than most people so it's not much of a change for me.
