I like the available helms that can mask whatever helm you are wearing.
I use the skull-helm, the top-hat and the ninja mask for separte toons.
I also love how I can wear various helms and the cosmetic helms mask them.
NOT so with the armor skins.
The armor skins LOCK on to that particular armor.
I would like to see the armor act more like the helms and be usable for a variety of armors thoughout the characters life.
Overall, more COSMETIC choices at a nominal (free) cost would be ideal.
Perhaps someday we can have a CLOAK or CAPE animation?
