The only one that can one hit kill is those which stick. Every other one will lower the health a great deal, but will not kill. Regardless of staying in or not, there are none the hunter has that lingers or kills with one blast aside from those which stick, and must stick to kill. Yes, I have 3 hunters, doesn't change the fact that they are the weakest. I enjoy playing as them and I can gear them all together. I already made and maxed out the other classes and do not enjoy the play style of them, thus deleted them. They are easily stronger than the hunter though without a doubt.
