I'd like to at least see one of each type (maybe a void handcannon [upgraded Word of Crota] and a Solar pulse rifle). And I'm fine with them being exotic; if you want an elemental primary, that's the prive you pay. Also, I think it would be cool if there was a quest that would allow you to put a burn on No Time to Explain, maybe something involving the Exo Stranger. Given the amount of effort involved in getting it, you should be able to make it awesome in the way you want it.
