Polish idea for Tier 3 (Patreon)

Ok here is the thing and I can make it work I think, Im not going to increase the price of tier 3 but the limited characters are not going to be available forever, the idea is  all the limited characters are going to be available again when I release a new limited characters but they are going to be gone when the time expires, what do you think?

I think I can gather all the characters for this month if all agrees
