I am not a fan of it being removed either, and I rly still don't understand the people going on about the animation lock.
The reason why you died wasn't because of the lock, people need to stop blaming the game for their own mistakes.
I don't believe that there was any situation where someone used it and died *because* of the animation lock, but there probably were a lot of situations were people like to believe that they did.

Dream Within a Dream just felt way better with Assassinate imo, I liked the extra ogcd and it felt cool to use.
