May I ask riot WHY fiora CDs are so high?

"LOL you think THOSE are long cooldowns"?

no jungle fi thats why

Because she's an AA'er, not a caster. She isn't supposed to parry an ability or AA every 5 seconds. Heck, I don't know what the cooldown is for her dash, but just recently I was playing against her and she dashed 4 times from their inhibitor tower to the tribush on purple team's bot lane(by Gromp). So, that's probably with the extra dash, maybe a 10 second cooldown? Maybe 7 or 8?

Long? The only one that's really long is her W, and that shouldn't be any shorter than it already is imo. I build Lucidity boots on new Fio and at max level without any additional CDR, My dash is on a 7 Second Cd, which is reduced to like 3 seconds if it hits anything, my W is on a 15ish second Cd, my E buff (Which is also an AA reset) is on a 5 second cd, and my ult is on a 60ish seconds CD.

I don't consider those CD's high at all, not to mention she doesn't really go mana-less unless you reaaaaaallllllllly either spam your abilities like nothing else, or stay in lane foooooorever.

Also, her Abilities are plenty strong, her Passive Scales with AD, which means endgame you're doing 10~15% Max HP True Damage per each vital hit, in addition to the attacks normal damage. Hit a Vital, Ult, Hit the same vital, Dash around them, hit another vital, that's like 30% Max HP True damage, + normal AA damage, + a guaranteed crit.

I may not be a pro, or even a moderately high ranked, (I don't play a ton of ranked), I'll admit that. But I don't think new Fio is by any means weak, just uses a different playstyle/build now, and has more counterplay.
