You guys asked a natural physic motion for metin2, and you were granted, despite metin2 and law of physic does not go along too much. But as i feared it is not about physic, it is about the fact that now you lose instead of win. And it is sad. Archers and Heal mage have two skills that raise the movement speed, by stucking them like you did in the past, these skills are useless. And no the solution is not to give them new skills, is to not let them stuck lol.
Also bare in mind that all classes had unfair power up to compensate the brain damage idea of adding 700 AC and 300 AP with bio quests, so even if now you may think some class are stronger than others, it is because the balance is not done yet.
