I tried the QMR build yesterday and totally got owned because;
1 - Glacier Hazard (Bees!)
2 - my decoy pugs had trouble staying on their feet, making my agro dumping skills obsolete
3 - swarmers
4 - double banshees
5 - my FQE isn't immune to brute butt wiffs (it burns and staggers)
Mission Status; Wave 7 Failure (was going to give up on wave 5, but though I could at least solo the pugs to wave 6 pay day)
Anyway, lots of work to learn this kit due to squishyness and me being a magnet to the poorest pug lobbies in the galaxy (yes, I play with some pugs from Andromeda galaxy too). Lucky thing for learning CPU. Only thing I have against this build is the Arc Pistol since I like to use the same finger for charging and Sabotage.
