She is not bad late game, but her early game is terrible. She also needs shorter cooldowns and some tweaking to her abilities. Maybe have her Q make her untargetable, raise the damage to 60/90/120/140/170.Her W needs a longer duration and a shorter cooldown.
Make his W do some damage and have his ultimate target an enemy and stick to them.
3. One of the rarest champions ever.He is bad early game and worse late. He needs a rework were maybe one of his abilities summon a ghoul and the others use his shovel or some thing.
4. One of the worst supports in the game. His W should also reduce the cooldowns of nearby allies. Time warp should slow maybe 70%(maybe that s too generous) of an enemy's movment speed.
