Personally I think exotics should only be modestly better than legendaries the [i]majority[/i] of the time, not blow them out of the water in almost every situation. There should be certain situations (think Spindle/ToM in the raid) or playstyles (highly aggressive play for TLW) in which exotics should be much much better, but I don't think they should make legendaries completely obsolete. Take Thorn. After it was buffed it had essentially no drawbacks. Looked cool, very interesting backstory. It was accurate with stupid range for a HC. It didn't require super careful ammo management as one clip could easily kill multiple targets. It disoriented your enemy. It just about gave you a wall hack as the DoT ticked. This made it exotic before you even factored in the DoT which broke the class by making it a 3 or 4 [u]bodyshot[/u] kill with a RoF that had no business being able to do that. Pair it with any secondary you want, who really cares. No legendary could compete with that, ever. That's not what we should look for. Contrast that Tlaloc, when the exotic perk is activated it also fires too fast for it's shots-to-kill. However, unlike Thorn, that ability comes at a big price: You can't use your super. Not everyone wants to make that tradeoff so it's not abused like Thorn. But it's still a good weapon in the right situations and if you want to make that trade. If you don't, you can use a Hung Jury, Tuonela, etc. That's how exotics should work. Can be amazing, but not all the time in every situation with no tradeoffs needed.
