well to tell the truth no exotic is really necessary but as the Mida was my first exotic in Y1 it is what i am comfortable with I do use Colovance's Duty and Red Death also as a Primary but for PvE I always seem to fall back to the first Exotic i ever got. The Mida Multi-Tool and it helped me survive longer in Y1 PvP when every PvP Tryhard was using Thorn to spawn kill me :-)
