It's so bad, that even with arc burn it sucks. You think 300% damage bonus would help it, nope 300% of 0 impact is still 0 impact. The thrall explosion is about the same damage as a grenade. My last exotic was the thunderlord... I got one, then I got another the same day and 2 more the next week... Yeah... You will get it, then like 30 more copies of it.
