We have 16 Troops at the moment.
With your Idea there would be to many different possible troops. It would be to difficult for Supercell to compensate the offensive and defensive strength. It is already complicated withe the 16 troops and all the defense we have at the moment.
I reckon for you:
If the Fusion-Tower would be able to fuse 2 troops together there would be "16 over 2" possibillities of new troops(itīs the Binomial coefficient). So 120 possible troops!
If the Fusion-Tower would be able to fuse 3 troops together, there would be 560 possible troops!
And if you could decide if you want to fuse 2 or 3, there would be 680 possible troops you could create!
Impossible to control the offensive power with that!
