Be nice if you couldn't sign up for war without an xtal and if not used you don't get rewards!! If you win the xtal is refunded!! I know that would cut in to the devas pocket book but hey give a little back
Or maybe just increase rewards a bit for xtal use to encourage it. But yet allow those that don't want to a chance at wars
You gonna buy me xtals op? If its xtal time and my side is winning I'd probably not xtal (low on them) after I use what's left I have to buy more. Which I can't afford. So yeah. War xtals.
You do realise that for a lot of wars, using an xtal is either not needed, or will simply give the other side plunder. This whole idea you have here will force people to change their strategy for these wars or people will xtal without being told to so they can get their rewards. And if someone doesn't have an xtal for a primal or round war, then that's your clans fault for recruiting off of wc. If It's an indi war them that's the risk of allowing everyone to war, you can either suck it up or try to move up a size bracket so you have less of a chance of getting these kinda people.
