Well i think its obvious but palas and knights huge underpowered... its why 90% of players are sorcerers... What realots did to balance this was knighs and paladins could use hmms by level based so they actually had more than a 40 damage pvp attack, but for paladins they could also purchase throwing stars, they were 5 gold each and broke every shot but they were 5 damage more and you could wield a shield, possibly the smartest thing ever to balance them, its like adding assassin stars but way less damage, 5 more isnt noticable, but the being able to use a shield is, plus there less capp so they can actually go on decent hunts.
Anyways just my suggestions so it stops being 90% sorcs online
