League of Legends (LoL) Question: Fiora state

Tank Fiora can work since she has a much higher likelihood of activating her ultimate in fights which could be crucial. In another way bruiser or dps fiora could be needed if the ultimate is easier to proc via outright killing the ulted opponent. It's hard to say which is best since it varies based on what you're against.

Not top tier but can be good if the player invests time into learning her. Typical build is Hydra into Cleaver into full tank, she deals plenty of damage with that. Full glass cannon won't work as she would just get bodied by tanks even harder
