- Boss requirements some boss should make it like a gym battle, like fire type against fire type, or require 6 pure type pokemon,...
- Difficulty more reward for kanto bosses, guardians (guar reward sometime reward TM and don't give money make me feel so bad ~~). Some boss's pokemons should be random order.
- Cooldown it's ok at all, but there're too many bosses. I suggest some of them should be 24, 36 day cooldown with extra reward :>
