Ornn's Ult Has Several Bugs
The visual animation for Ornn's ult (at least from the Ornn player's perspective) almost feels random.
I just played a Co-op vs AI match to practice Ornn a bit, and this ult is next to unusable. The ram either spawns half way down the path and runs past you, making it impossible to tell where the real hitbox is, it speeds past you like a rocket, or the 2nd cast just doesn't even happen. There have been several times (without being CC'd mind you) that the re-cast for the headbutt just doesn't go off no matter how many times I press the key.
This is honestly one of the buggiest spells in the game right now. I don't know how it looks to other players, but as an Ornn it sucks so badly because we can't time our re-cast or the re-cast just doesn't happen.
This wasn't my 1st time using Ornn mind you, I was just getting my win of the day.
UPDATE : I'm in Practice Tool and is working fine, so it appears to only happen in actual matches (PvP or vs AI).
