Hero's Arena and alliance quest.

This game can be more interesting if we can include a “One on One death match” between 2 Strongest heroes. Like a simple street fighter or Pokemon battle. ???

Another thing is, after a war and quest, an alliance can figth together agains a very strong Boss or island in certain period of time for an exciting rewards. ???

I am sorry if someone already suggested this idea and i am just repeating this again. 

Thank you…
