Although I'm neutral about primary elemental damage (other than the fact that I would not use Zhalo if it weren't for arc damage), before I'd make this change, I'd make the other Class exotics equivalent to the Tlaloc. My Warlock used to be my third choice for Crucible, but because of the Tlaloc, I love melting guys with it when I have my super. My k/d sucks, but since converting to the Tlaloc, my numbers have been slowly increasing. But the Ace of Spades and Fabian Strategy are just kind of meh. I'll use the Ace of Spades if I need to do the weekly Crucible bounty if necessary, but the Fabian Strategy is just terrible. Neither of those two guns do anything special, compared to the Tlaloc. I wish the other two exotics had some special perk that suddenly made it OP, at least for awhile. Get the other class exotics fixed before we look to improve the Tlaloc. Give it solar burn, if they do. :)
