I have the same roll but instead of stability MW I got handling, I put on an adept range mod boosting to 78 (88 with keep away) sitting at 48 stability. Isn't 68(78 keep away) kinda low? Range 37.50m vs 38.88 of 88 range.
remember that precision instrument gives a little bit extra effective range too. Mine is 97 range with keep away and I rarely find myself engaging in fights where I'm winning becuase I'm out ranging people. Most maps just don't have the geography to take advantage of igneous's insane range. I'd say maps like midtown, vostok, multiplex, and bannerfall are some of them but the new ones are all much closer range
