Yeah, I wanted to separate them along a 1:1 class/class divide, and while I had people suggesting that Scout should be a Rogue, it didn't fit. Not only is there nothing furtive about his fighting style, but the obvious choice for Rogue was Spy. XD
Scout a Rogue? Naaah. Rogue would definitely be Spy. Some of the obvious classes would match up like that, Sniper as a Huntard, Soldier as a Warrior maybe, Pyro a warlock if not Mage if Scout would've trade places perhaps [warlock suits better though], Medic a Priest, and Demo as a Paladin lastly.
Hahaha I hope I got everyone with added of your own. Just some thoughts, but see the divide.
I saw Solly as the Paladin, (obnoxiously zealous, provides proximal buffs) and Demoman as Warrior, (has a charge, masterful use of swords and axes) but aside from, that, that's how I had it figured. That and I like the idea of a little Pyro wearing the Dark Coven armor with the gingham witch dress and pointy hat.
