I'm sure ppl would love the opportunity to be able to buy a gender change.
This I believe would be a highpoint. Yes it wouldn't work for ppl who don't have the be any race with any faction bought. But it would open up the opportunity to combo the two together in crown store allowing ppl who have the any race with any faction to be able to min max their racial attributes. This would be great and I'm sure many would appreciate.
New Hairstyles/adornments/facial features(beards,makeup, etc.)
New customizable features for characters would be fantastic.
New Motiffs for armor and weapons
I'm sure ppl are ancy for newer ways to mix and match their appearance.
Theres a dragon in the middle of cyrodil that looks very badass. I would love to be able to have something like that as a mount, wether it be a crown store item or a very rare drop from a high level dungeon and or very hard achievment to aquire that rewards you the dragon.
More ideas to come, any1 with their own ideas are welcome to add to it. Hopefully devs have some nice feedback for us.
