I've been playing a lot of Demigod lately, especially since the Demon Assassin update, and I had a thought: Why not put Demigod style PvP arenas in games like Aion, WoW, WAR etc? It would put everyone on the same starting level regardless of weapons/armour/items. It would be challenging and fun, but most of all fair.
For those that haven't played Demigod, you basically choose a god (each have diff skills/abilities), join a team and then fight against another team of demigods. Everyone starts at level one with no weapons or armour and you gain XP and gold by killing waves of enemy NPC grunts that come from gates (in the bases), capturing flags or killing other demigods. Each time you level up, you can spend one skill point. You can also buy weapons and armour with your hard earned gold. Each flag you capture has a different bonus, i.e. +15% Health/Mana, +20% Skill Cool Downs etc. Flags can be recaptured at any time provided they aren't being defended. The ultimate goal is to destroy the other team's citadel, which is defended by destructible guard towers.
Now lets apply this PvP game style to something like WoW. Each class would be the different demigods. There could be 16 levels, with 5 skill points given per level. Everyone has a very basic starting weapon and no armour. You can buy/upgrade these in the game as you earn gold from killing NPC grunts, capturing flags or killing other players. The grunts could start as Murlocs or something and slowly level up as the game progresses. They would spawn from each other's bases and meet in the middle.
I definitely think it would work and it would mean you wouldn't have to grind endless hours for levels and items just to enjoy PvP. May cause a few care-bears with epic loot to cry though ;P
