Fusion building

i would like to propose the inclusion of a fusion building. this building will require 3* to fuse 4* and 4* to fuse 5*. i will also add the posibility of using duplicate 5* to fuse a Hotm for example. what does everyone thinks about this idea?

I like it, but fusing 5* material to hotm… How will man ever have enough 5* material for 5* ascension. I prefer different material for fusing hotm, like “elemental stones” perhaps.

I like that idea. I’d also like a lottery system that allows you to trade or fuse extraneous troops for something random - mats, gems, troops, heroes, even. Requires three or more troops and a spin game with random outcomes. I have a huge buildup of useless troops in storage and nothing to do with them.
