Fighting Heroes

Hi, sorry if this has been brough up already but I couldn't see it anywhere.

I'm trying to get Hero rank and from what I read on the FAQ it says from a Guardian I have to fight a Hero. I have all the players 100% but no matter low long I play in the last arcade can never come up against one. Am I fighting in the wrong area or do I just persavere as there are only three of them it's going to take a long while to come up against one?

Any help greatly appreciated,

 

Click the RANKING FAQ link right above your post. The answer is at the end. You don't need to fight one of the three Heros to rank up to Champion - just win against 15 Guardians in a row.
