Would be cool if temporary rewards were just christmas gifts with tower-themed items/hats (horns, wings, masks, helmets,---- whatever. Not saying I personally like those kind of hats, but it seems to me that's the kind of trend we've seen with tower-hats )
Earn tokens as a guild for various things like total guild-kills milestones, Tower Hours, etc and redeem them for a present or two. I don't think this is extremely hard to code; but who am I to say?
Also, this would fix "noob recruiting" as they would earn temporary tokens too.
