I don't know if this has been suggested already, but in a future update, could there be a way to organize our heroes, so the ones we want to focus on building up are grouped together, up to 15 heroes possibly?
Also, can it be made that when filtering the heroes, the Roles filter actually divides them into their role groups when selecting for fights. I get they are divided, but the division is not clear unless you've memorized each character's role. I have memory issues, and these suggestions would be extremely helpful to people such as myself. Just some ideas
