The Developers hinted for it to be released in Season 3. Don't think so that they're working on it though. Support Anyways!
This is a more importand feature of the game than banners plz devs dont back down on your promise and release the war xtals!
From original thread to now and still not implemented. Plenty of support and legitimate reasons for adding, and won't affect income for devs...
I'm gonna have to say no support. Option is to only buy 2 per week and at the equivalent price of roughly 15 mith. If availability were tweaked to remove the not real money purchase limit and the price brought down then support.
