So you really wanna let 35lvl my old friend Bushido fight against poor 30lvl multiaccounters?
See my earlier post:
Unfair xp gain/leeching? You have to fight with your fists (no gloves). Alternatively: Every piece of equipment (an armour piece, a weapon, ammo or a horse) you equip lowers your level by 5. Naked and a weapon? You lose 5 levels. Body armour and a weapon? You lose 10.
