How about more interesting things? Still play up the support class by all bullets fired out of the bubble [i]at a teammate[/i] grants them small amounts of health (or shield)? Bullets can pass through the bubble but at .5 damage of original value and damages the bubble the more you shoot out of until broken? Can instead fire guardian sized bubbles at targets instead of a normal ward of dawn to render their guns useless until it wears off (aka theyd just be shooting at the inner walls of the bubble. Bubble would move with them etc)? But just straight shooting out of bubble would be a bit op, especially when you get a 6 man defender team up. Also dont get me started on all the pve cheese haha.
