Yea but there are weaknesses too:
Yasuo is punishable by a freeze lane thus his E puts him into trouble only and non adc ranged champs can safely poke him which I always do on mages.
Fizz finnally got the exact nerf I want so his double E with hourglass finnally got hit otherwise he's dealable with poke and freeze.
Ekko was just horrible design, an assassin SHOULD NEVER have that W that's a dam tank skill first and foremost it LITERALLY was miles better when ekko went tank. Most obvious power, it's a giant zoning AoE stun which slows, it's 1000% more reliable then a shaco box ofc it was a bad idea by itself. The damage % bonus on targets is fine but not that stunfield in it's entirety.
I just wish i wasn't a noob back when ekko was released and called riot out on their BS cause they removed silences and stun eve cause it was an issue but didn't think an AoE stun field would be(but then again silences and stun eve didn't go tank so as much as I think their logic was poor I can't really blame them for not seeing this happen.
Enough about ekko onto zed, that was a knee jerk reaction in it's entirety his win rate LITTERALLY did not even change QSS change only affected the ADC who shouldn't be alone anyways, duskblade passive is just normal damage yes it might be additional but it's normal damage. If riot didn't increase his shadow range zed's main weakness would be more obvious to players that he's easily punishable with shadow used.
But yea my nerf suggestion for zed was simply remove his passive from working on winions and move his slow from his E to his passive that's it. His slow adds too much to his escape/gap close ability when he doesn't need it and it doesn't affect his q combo at all.
LB- Meh my main concern is she has too much early game but 0 late game and needs a rework imo. Her W needs to be reverted back to it's CD starting when the move ends, after that her Q can be changed to being a passthrough skillshot mark and they move damage from W to Q since Q could be waveclear instead of W. Those changes would fix all of LB's issues and issues of facing her entirely.
TL;DR- Yes I asked for nerf/rework suggestions on 4/5 of those champs but I don't think it's fair to just fully note just strengths for some of them.
I couldn't care less
