I totally agree. I never wanted one but ended up getting one in Nightfall. Pyromancer is a great perk and to be honest if you need tracking to succeed in a raid you are a total noob. This isn't the best in all situations but great for bosses that don't move much, crowd control and GREAT for The Abyss. Shoot it on the pathways when thralls are coming and thats that. It clears the way and your team gets to regen some health. I even enjoy this for Control in PVP when a group is capturing a control point. Just crank up the velocity.
