So we already got a taste of limited time holiday themed costume items with the harvest masks. I think it would be neat to expand this into limited time weapons as well.
Let's say for December it would be a freezing vortex bomb that makes a sleigh bell sound when it detonates and looks like a snow storm, I dunno. It doesn't really matter.
The main idea is that you'd be able to buy it with holiday themed tokens throughout december. Tokens you gather in T1 can buy a 1* version of the weapon, T2 for 3*, T3 for 5*. The weapons would expire from your inventory after January 15th.
Well I would like to keep my hard earned weapons for longer than a month Hmmmm what if they went back to the original version of that weapon on the 15th?
