There is NO PROFITABILITY when it comes to spending gems bcoz they are of no value and neither are the items you receive by spending them. However, there are efficient ways of using your gems to acquire items in game.

I agree with upgrading the training fields. Also upgrade armorsmiths (3-4 its up to you). It will help with crafting, enhancing and helping your guild aquire bonuses faster. As for the chests, that is up to you but I advise AGAINST them unless there is a 90% or higher chance for Epics. I save up my gems for boss collections since there is a time limit and the rewards include a free armor like the GKale. Also, once in a while I will help refill my energy in GW. I used to use some in Arena, however, the missing has become ridiculously frequent so I just quit after I get the 20 free gems.
