Now I am having both heroes level 20 what should I do ???
1- upgrading them level by level so queen 21 then king 21 then queen 22 then king 22 ...
2- upgrading them 5 by 5 so queen to 25 then king to 25 then queen to 30 then king to 30 ...
3- upgrading them 10 by 10 so queen to 30 then king to 30 then max queen then max king
4- max queen without upgrading king then max king
please tell me what I should do by voting for one of the four choices.
Thank you ^_^
