Sion's bugs (show him some love Riot, he is already weak as it is).

List of bugs: -If you level your W at level 2 while in your undead form, the health won't stack properly until level 3. You miss out on a lot of early game health doing this. -Sion doesn't have a tiamet animation, he just stands still while the cleave circle comes out from him. And yes, tiamet is a viable item on Sion cuz it builds into Titanic Hydra -When doing blue buff and using your Q, the blue buff will lose aggro and reset itself, even after the laners have finished their leash and left. This has happened several times during ranked games and I end up behind because the buff resets twice. -if anyone knows any other ones, post them in the comments Also he should be immune to CC in his passive form. It's basically useless the enemy is blind during a teamfight. In all other situations its just a way to get a few CS.
