Ive been building rav hydra, but lategame i feel like my 2.2k health is not enough at all, Should i be switching to titanic? I actually prefer titanic in general on champions
2k @18 is pretty much the average for most champions, which is essentially pure squish.
Fiora does not have the kit necissary to reliably make pure squish work.
Her kit is set up, well, almost exactly like Irelia's. Ideally you want 50% offense, 50% defense with itemization.
Also i've been doing Ravenous-->Black hydra--> iceborn gauntlet. That way i can buy merc or ninja tabis instead of lucidity boots, also her Q applies on Hit effects and its been working out pretty good considering fiora gets blown up easy. Then id go into maw or something.
I'd recommend closer to 50% defense, 50% offense with Fiora's build. That build is more 33% defense, 66% offense: and with only 33% defense, you'll still get blown up for the tiniest mistake. 50% defense gives some staying power.
is GA a must usually? I find myself needing GA
GA is pretty much the best 5th major item on every single champion in the game, and a really solid 4th major item on most.
Within an average 3 major item game, it's not a must though, as most games don't drag on long enough.
