At the moment, when you click on the profile of a former player or just yourself...the front page will have " Featured hero, Most successful heroes 1 , 2 , 3". My suggestion is that at the moment the most successful hero icons 1 , 2 , 3 are the heroes with default costume. I think it would encourage players to get skilled with a certain hero and also to make them purchase bundles / keys to buy alternative costumes if they were to have / show the players current equipped costumes on the players most successful heroes tabs.

example:

My most successful heroes list.

1. Meepo
2. Phantom Assassin
3. Bounty hunter

So for example, at the moment my most successful hero on tab 1 is meepo and it is only showing his default costume. From my suggestion...I suggest to have that meepo tab 1 on my profile to be wearing the "Riftshadow set" instead of its default. The same goes to other hero with full costume gears.
