Will we see more GC ranks before expansion?
So GCs are kind of...meh at cap. Sure, you can buy gear for leveling with the credits, but for the most part, there's not too much benefit (I'll admit I don't know anything about PvP so for all I know, it could do something there.), and if you did a search for it, you'd probably find a ton of people at cap.
I think that the ranks First Lieutenant and Captain should be opened. With the expansion coming early next year, my ideas for what you can buy at these ranks, they should be added sometime mid- to late-2.5 cycle, and I know that my item suggestions will get me a bit of hatred, but if the story of our relic weapons is to continue in 3.0, then I think just before the expansion would be a good time to add atma and alexandrite (or at least alexandrite maps) to get ready for the new content. If you really want RNG to be a thing, make it a random atma bag or something. Make them cost a good bit too.
It's just a thought. Probably a bad one and one I'll get flamed to hell for by people going "the game's already too easy" or "lazy noob" despite me suggesting it because people already complain about how they'll have to run old content and this is just a suggestion for an alternative.
