State of Nidalee 5.2
If you look at pickrate/banrate/winrate on nidalee, she is definitely top 15 maybe top 10 in terms of power and still rising. Riot is probably eyeing her in terms of balance, despite the low visibility of her power level (just like kassadin's low power level visibility) and the recent buff (just like ahri's recent buff). I think it's fine that someone is in the top tier. I also know that her teamfight ability is terrible. But she has great hidden roaming potential with her movespeed buffs and free dashes, and has the most frustrating laning experience. Think it's time for a nerf. Before you say qq more, I have not faced any nidalees recently, but have had many terrible experiences in the past. Watching cowsep slamming his keyboard right now just reminded me of her problems.
It seems like she is a little bugged as well. When she leaves/goes into an unwarded brush, she remains untargetable for a longer period of time than other champions. When she ducks in and out sona-style, it is harder to auto her back before she disappears into the brush, compared to Sona. This is based on personal experience not empirical tests (or intrinsic analysis of code).
