@DoctorStrange I think it’s because people were hoping that the costume feature would be a good and useful feature; those offers you’re talking about don’t affect the game in any way, they’re just offers. Costumes are an addition to the game mechanics, so it would be nice if it was done in a better way.
Personally, I’m not mad because I see it as 2 additional chances per month for an HoTM for free.
But it would be even better if costumes worked the same way as Troops; 150-200 gems per pull, feeder costumes (could just be a generic 1 star and 2 star feeder) can only be obtained through silver tokens or costume tokens, and costumes can only be fed by feeder or other costumes, not normal heroes. Costume tokens can also be obtained through mystic, wanted missions, recruits II (or a similar quest)
This way it gives incentive for paid players to buy more costumes to feed to level costumes up, but also makes obtaining costumes viable for most players like most players can obtain 4 star troops.
