Cool Down 2h to 1h
Since there's a lot of bosses now it's hard doing them all in one day. Maybe you should consider lowering the cd-time on bosses in elf city, ice hill and dragon valley from 2 hours to 1 hour? It would be logical that the cd increase with the degree of difficulty, and right now it's frustrating waiting for 2h after playing the elf city boss which can be done in two or three moves for a high level player.
