This is only going to get worse, but i guess having this issue is going to take our minds off of how the floor is being raised with the new bash changes, along with animation canceling being destroyed. At one point it was said to be a feature(Animation Canceling), just like how activating an immovable potion will negate other players from interrupting your resurrection.
Which is the worst bug ~ "feature" in the game.
