Upgrade Item drops from upper tier units

[BatmanSK]

I think that the drops dont need to change if developers want them to be like this, but i suggest add to the find more function that it will show mobs with the best drop chance for each loot. If the best mob for some loot wont be there, just make it find the mob that is second best to drop it. Or either make some thing where we can see drop rate for each loot and who is dropping it
