I've toyed with them as I've gotten them as drops but until MIDA they've not been my main go-to weapon. I'll use an auto rifle or a fusion rifle if I know I'm going to be in really close quarters where I can't take advantage of MIDA's mid to mid-long range superiority or switch to Thorn when I'm playing in Crucible. But when I'm just out on patrol in the wilds I'll be sporting MIDA more often than not.
