How to get better heroes, stuck on 3 stars
I just started this week, so I have 4 3 star heroes to max level 30, all 4 ascended 3 stars ... where do I go from here? I am stuck on the dungeons and campaign as my heroes cannot get any further at their levels.
What should I be doing to get better heroes, or making these heroes better? I am trying not to waste a bunch of good stuff on these lower ranked heroes, but I am also F2P so I cant just go buy new heroes like most. I also see that I will get 3 4 star heroes at 30, 60, 90 days ... should I just grind something specific like dungeons until 90 days and then work those heroes?
Thoughts?
