Tlaloc is meant mostly for Fireborn Sunsingers who hold their Super as long as possible. So I say it should do Solar damage! That would make it more unique and appealing
Ace of Spades should be Arc, making it a successor to Fatebringer.
Fabian Strategy should be Void, just so there's a reason to use that POS. Also Defenders don't have Void abilities besides their grenades, so this could help them out
