When you realize how good trip mine grenades are, and how to use them in pve, it really isn't a bad exotic. It isn't the best, but it isn't bad. Looks the best though! For example, on Confluxes in the raid throwing the trip mine grenade in the cave on right side works wonders, on left side throwing it in one of the paths for the same. Even better when you attach it to the wall instead of the ground. Plus during the lulls in adds, the extra time would be helpful. Personally I get grenades way fast so I use it constantly. By far trip mine has become my favorite grenade.
