personally i think poms are better in a qv than regulars, you carry almost infinite ammo and the amount of pom fire on a qv is insanely powerful if you know how to use it.
in my experience pom are not that great by l1, good enough to shoot scouts and the occasional fighter, by l2 its decent to take out any scout and a bit better with fighters.
by qv however it seems like a drastic change, to me they dont just move from decent to good, they move from decent to holy crap!
