I have a commercial idea for visual design - I'm a designer and pay attention to such things.
For most tournaments (which are a gold dwelling for everyone ) are given skins for the characters, but there is no systematics, in the "magic cupboard" a frank mess!
I propose to create "Tematic Skin Sets" by attaching them to the themes of the last chapters, namely, angel skins, demonic, necrotic, pirate, forest, arctic, knightly and so on...
For many sets there are already blanks, it remains to add more characters - and put up for sale!
It will be profitable for both you and the players - the set will be cheaper than buying each skin separately + personally I always wanted to equip my fighters in the same robes.
I started with a pirate theme, it's the 16th-17th century, and I drew a skin for the Dracul (my favorite) "Venetian Masquerade", Lady-Dragon, named "Lady-Captain" , "Cheese Cook" - student, "Yeti-boatswain" - Electroyeti and "Grumpy Jung" - Witch Doctor, and the last I imagine is a Centaur-Dothraki.
I hasten to the birthday of the game!
