You have to beat it at its own game I think. You might still get frustrating results, but it won't be a personal insult anymore 
Oh, I use that too sometimes! Can be a lot of fun. But I can hardly complain about bad map/enemy combos when I'm running a Spitfire Asari Vanguard! And it's surprised me a few times with weapons that I thought would suck on the kit, but instead the cooldowns/clip size worked out perfectly for reload cancelling.
This is exactly why I take some sort of secondary weapon on gimmick range kits. If you're focusing on CQC, at least take an Ultra Light Locust so you're not stuck waving your fist around at those Rocket Troopers while you're sitting in the Hack Circle. Or if you can't safely cross an open area like Hydra or whatever.
Yeah, I felt pretty stupid loading into that match, only to realize that I had forgotten to grab a light longer range secondary. I usually default to an Ultralight Eagle on most CQC kits, though I imagine the Locust has much better stability.
