The damage, the sustain and the CC is just way too much for one champion. The nerfs she received a while back werent nearly enough. This champ has no bad matchups. You pick a kill lane - no worries, she'll heal right through it. You pick a scaling comp and play it safe - no worries, she'll combo you with ignite and kill you. So you thought you could just pick a CC support to deal with her healing and damage? No worries, she'll out CC you and be impossible to catch after level 6.
This champion is overloaded and fundamentally broken. The 13% pick rate and 53% win rate is enough proof. Nerf this game-warping freelo champion already.
