Why thank you very much for saying so! =D

Like said, this loadout does struggle with Dreadnaughts, but it does great on Sabotage missions. For Dreadnaughts, I go with eitherome of these two loadouts: https://karl.gg/preview/17050#/

V.I.R.?

Oh! You mean Volitile Impact Reactor! I actually tried that overclock a couple times. It did it's job at area denial via Sticky Flames, but didn't quite feel like the single target weapon I intended it to be. But that's just my preference. You could give that overclock a try for your own gameplay, if you want.

It could work, if you're good enough. The absence of EM Discharge can make it difficult, but as long as you keep your turrets loaded and plant your proximity mines in the right places, I think it can be done.

You might have to mod the Stubby a little differently, too. Perhaps 2-2-1-2-2 to make the best use of the Tier 5B effect for crowd control. Give that a try, if you want.
