Chain Trigger for Gunner?

[Sp-24]

You can use Chain Trigger with any weapon, and even switch between them mid-chain, provided you (and your internet connection) are fast enough! Rifle combo only seems to deal 9 hits, as opposed to machineguns' 10, but I guess being able to move in any direction you want while shooting is also a valuable ability.

Quick edit: I've tested this on Dagan, so some 40% of shots may have missed the target spot. If rifle's full combo is 15 hits, then I guess it's pretty good for chains. But, then again, machineguns have a Gear skill that also powers up PAs...
