Who would you guys level to 80 first?
Kunchen. Obakan is not particularly effective.
I, and my wife, love Obakan.
It depends on your current 4* 3.60, 4* 4.70, 5* 2.60, 5* 3.70 roster.
5* 4.80 heroes get all the attention, but 4* heroes are the backbone of Empires.

Obakan and Kunchem may both be dark 5s, but they are completely dissimilar. What will you be using the winner for?
