The portals containing trainer heroes are not for those of us, who are new to the game, and still want the regular heroes.
I would advice you to use your summons elsewhere. I am. Because I know I will be rather frustrated, if I get a trainer hero, after spending hours upon hours gathering the coins to do a summon.
I will still echo what I said, when this got implemented.
Give us a choice.
That way both new and old players are more satisfied.
We get it. All these new events, new heroes, new Season. It’s to keep your long term players engaged. Yet I see no reason, that both player segments cannot be heard and seen at the same time.
