We have a lot of heroes from events, seasons. We have them more and more (and probably there would be even more), especially new 3-5* heroes.
But beginning players are having still not so many heroes to have.
Please, SG make new, additional pack of basic 1-3* heroes. It might be only two heroes per star level.
It might vary a beginning of the game. I remeber that beginning was very monotonous because every player in lowest rank were having th same heroes.
Also there might be added some 1-3* atlantis heroes available with Atlantis event. (Player can pull daily summon or use summon tokens to have an attempt of getting Atlantis 1-3*.
