Her Q Hitbox is ridiculously huge and her E is obnoxiously hard to get through. I really like the fact that Janna could actually do damage, she was played in LCS as a Mid laner back in season 3 once but I still hate the fact that she ended up rooted a support.
Mysticman891 votesQ max Janna was super uninteractive completely safe perfect wave clear so it got nerfed to oblivion. W max Janna is very consistent poke, but not terribly safe due to lack of E uptime, since E CD got nerfed heavily, and especially with the upcoming nerfs make her even more vulnerable when she uses it. E max Janna offers almost no pressure and will probably lose tower, but will keep herself/carry alive.
Pretty sure her Q hitbox is narrower these days than it was once upon a time, and making it much smaller would make the visuals misleading.
BLIGHTBRINGER1 votesHer W damage + combined by the fact that she gets more damage the more movement speed she has rediculous scaling. I once saw a Janna that I assumed maxed W first, and at level 6 she dealt 60% of my healthbar with just her W alone with these items 
.
Her Q is dodgable, W is just point to click and stupid.
VoraciousX1 votesThe thing I hate most about Janna is snapcast Q. It should have at least 0.25 second delay.
