Here's a suggestion: How about you change the Banish skill so that instead of knocking enemies out of your own crosshairs whenever you shoot them, it slaps enemies who shoot YOU? I mean, banish as it is right now actually seems to help your enemies more than you by knocking them away from your fire, actually preventing you from ever ambushing or flanking an enemy. It would make a lot more sense and be more help (without being overpowered) if it gave a chance to slap the enemy whenever they damaged you. It would also be of some help against people who camp as humans because it would knock them out of their hiding spots.
Well, banish as it currently is wouldn't help in that situation either. Whether you're both shooting at each other or you're shooting them in the back, it screws up both cases. At least if the enemy were shooting you in the back, banish would help you in that case sometimes.
how about, instead of sending them out of your crosshair, you send them flying straight up really quickly, that way when they fall down they take damage.
