You need to stop throwing a pity party for yojrself and put some effprt into playing the class. Musa is probably on of your best matchups in a 1v1. Hell you have a grab. You think you're getting 1 shot w.o crust get caphras. You're getting 1 shot with crust, grab him. You have a problem with a class that has to have enough ap to kill you throjgh sa and even then can be beaten quite easily if your are smart. If you are in sa and a musa starts crust on you, you can 1. Grab him, 2. Tp directly behind him and throw a water ball.
