[Wardrobe access for non-premium players]

There has to be some perks and something like wardrobe for this game is a good perk 

it's better than locking dungeons, and other crucial game items behind the membership if they did that they'd have to make the game a sub game.

 

As long as the CS and perks of premium remain as is and doesn't cross the P2W line its fine to have a paywall form thing like storing costumes. (and it was one of the main reasons I got one that and the costume that came with it)
