It kind of feels like it'd be weird for your "champion" to be another humanoid. The classes are largely archetype-based, and thus not inherently balanced. If your champions were humanoid, it'd have to be between a different universal-classed avatar, or your normal avatar - but with skills you don't normally have with your normal class.
From the Wiki:
https://ashesofcreation.wiki/Node_governmentsMayors of military nodes are chosen from citizens through last man standing (gladiatorial arena style) combat.
=An idea currently under consideration is to have players build out a champion that they can then fight in the arena, rather
then using their regular characters. These champions can be equipped with gear and skills via quests, along with
materials and gold to make the champion stronger.
=The reason for the champion idea is because the game isn't balanced for 1v1 PvP. Utilizing champions makes arena
combat more of a level playing ground.
=Arena style combat is instanced but spectators may be possible through an interface.
=The winner of the combat can not transfer the mayoralty to another player.
Maybe the avatar for these battles could instead be a military-type beast that both contestants have little experience with? Yours truly feels that this would be less awkward than using a humanoid toon that you don't normally play with, or a stripped-down, universal-ized set of skills that your normal toon doesn't normally fight with.
