As far as gunsmith weapons, they have to make sense in the style. There should definitely be an Omolon AR seeing as How Hardlight is just that. But something like a Hakke fusion rifle wouldn't make much sense. SRL would be cool as a monthly thing like Iron Banner, but not as something considered content. The Spring update is aslo supposed to be heavy PvE and SRL in PvP, so I don't see that being in the update. But more weapon quests that are as interesting and well done as the ToM and Chaperone quests would be cool. Sleeper was convoluted and First Curse suffered due to the gunsmith timegating.
