I do like the idea of costumes in general. They have made the old heroes more desirable; atleast to me. While the new things they’ve added to the costume chamber is appreciated and does justify the gem increase it was not what many were hoping for when costumes were first put on hold. Not to be over dramatic but when I saw the price for a 10 pull went to 3000 gems my excitement for the feature almost tanked. Paying more gems was not what I was hoping for. My suggestion which some have mentioned before is to please add a 2nd summon portal to the costume chamber. Where it is only the costume and nothing else. A single pull should be around 250 gems and a 10 pull around 2000.
Portal 1 / Gate 1 - Hero, Costume, Ascension Chest, HOTM
Portal 2 / Gate 2 - just the Costume. With the odds of getting certain costumes reverted back to what they were previously.
