I really like heroes, but there are a good amount of things that I don't like. For example, the story is weak, but I honestly didn't expect a great story from a free mobile game so I guess thats not too big of a problem. I don't love arena, but I think it could be a cool concept to try in the main games, kinda like what we have in awakening and fates , but more of a ranking and rewards system. Another thing I don't love is the summoning. Since im a free player, summoning can get very frustrating, but I also understand thats one of the main systems of the game so theres not much to change there. the maps feel very plain and small. I would love some more variety and maybe just some bigger maps, but I doubt it would be as easy to handle in a mobile game.
