I agree! It will usually run up to target and keep running for full animation! You can’t break out of it at all. Sometimes it goes past the target.
I wish you could break out of it by pressing a movement key. Especially when you run up to the wrong mob and you keep running into a pack of enemies!
It would be faster to rush a mob , break out of it , and start attacking normally, then the 1-2 second lag it takes to actually hit the target with rush.
It should be a quick rush and strike, not run up to target and keep running for a second or so before striking.
