Removing unlimited transport and adding some defense to casters the solution?
Melee can trans as much as a caster and catch up to them, which is why melee wins the battle.
Melee arent supoused to be able to rely on trans but more on run attack to catch up.
Tele should cost more and knights should have less mp so they couldnt rely on trans before higher levels.
as i recall also fighters had trans wands did they not on xen? they didnt even have transport which was why they used run attack.
