Please, steal Wow's transmog interface and systems.

The Hideout Showcast is an amazing way to get people to buy MTX, updating the way you can view and show off Transmog MTX would only boost sales. Wow has the best transmog system to date and its community is only making it better.

I love the design of sets in PoE and would love to have a better way of viewing things before purchasing them. With the way the system works now, it's hard to see what you're buying within the game environment. If there was a preview option for the character I'm playing instead of a link to a Yt video, it'd be a lot easier to decide on what I do and don't want to buy. This is one of the updates I thought PoE2 would focus on but I haven't seen anything about it anywhere.
