Honest Fiora discussion

I feel like enough time has passed with this recent Fiora rework to truly get a grasp of her new playstyle etc. and it is extremely broken and anti-fun; I'd rather go against an old school proxy Singed as a half dead Teemo with no W and 5000 ping. Very little of her kit thematically makes sense, I understand the ability to dodge and parry, and being nimble makes sense, why in gods name can she block/counter attack something like a karthus ult or lux beam?

Her cooldowns as is are too low, her Q gives her insane mobility and chase potential, while her W gives her a cool .75 secs of invulnerability (and depending on the situation a stun) her E does a very large chunk of her damage and the slow was overkill. However the thing that wraps it all up is the nonsensical nature of her ult, she outclasses darius easily on her ult in true damage, while having a team heal that's more potent than a janna ult unless said janna is stacking major AP, what duelist heals their team, is she a paladin now? Did she gain holy powers? Her kit is too strong, and there's no real counter play, she has excellent mobility, very high damage with added true damage and a passive that heals her, an ult that heals far more than it should while dealing massive true damage and a very hard hitting 2-prong attack that slows. I feel this rework gave her far too many strengths at the cost of little to no weaknesses.
