I like it. but put a limit on it. Eg: 3 shots.
I kinda don't like the idea. TB and RT should be different. In RT you should't be able to fire single shots fast like that (TB is another story). But still if you have 14 ap you can shoot fast but you won't be able to do much damage with 10mm pistol. One my character with 14 ap and power fist with 25% critical (2 ap one hit so its 7 hits) does a plenty of damage! Or use .223 pistol with fastshot and brof and you can still do plenty of damage.
If you want to make enemies, try to change something.
I beleave that once that kind of builds start to roam hinkley and tc.
I never been in hinkley, just have some chars for PvE and I can say they do plenty of damage. In PvP they are nice (group not 1v1) but nothing special
