I'm with you on this, especially for bosses/enemies that don't move. Ir Yut, Spider-Walker in the Sepiks Prime Strike, and things like that. Other than that, I'd rather use my Ghorn to just kill everything. When it comes to parts like the lamps, everyone shooting them, killing with rockets usually does enough. If you need some AoE's, throw down a grenade that sticks around with AoE damage.
