I main a defender, but for crucible it is tempting to switch. Atm you can just run straight into enemy fire throwing hammers blindly in the direction radar tells you to and get double and triples you didn't even see.(I know Ive done this). My solution is to make the total health 75% of what it is now OR disable double jump and sprint. I feel that this is the counterpart to blade-dancer but gets range and splash damage so it should have to compromise somehow .
