I made a combo of Antigua+VT against wolvers on T2 and apparently worked well. The wolvers dodged less with shock.
But I made a run on a T3 fiend prestige mission and I made the combo of Valiance+VT and doesn't worked well. But I was a bit tired on that day, maybe lazy, and played badly. So, I want to know if this combo can be good or not.
The idea of the combo is reduce the chance of dodging, to hit with more facility.
EDIT: Grammar fix
Voltaic Tempest is highly effective against fiends. With that and just about anything else, you should be able to beat all of them except maybe greavers.
If you're worried about dodging, then the classic answer is Callahan. Its bullets are really fast. But to be honest you should wait for the supposedly impending gunner update, before planning any big gun acquisitions.
Alternatively you could just use Dark Briar Barrage. Or you could use VT with Final Flourish/BTB.
