Rebel King, Mr BCW and myself (of Crystal Knights) have put together a simplistic view on heroes and their talents for 4 and 5*s.
We wanted to produce a visual that may help you decide in choosing what hero to use emblems on.
Please bear in mind that the 3 of us not only looked at the Hero as a whole, we incorporated the Hero’s skill in making our final decision.
This is only “suggested”, it is not intended as a “we are right and you are wrong” guide. Naturally, it will boil down to your own opinion/preference; hence it is a suggestion.
