In regard to using Disarm, if it's in a duel and both players don't mind, then I don't care, but , I despise disarm any other time because:
1 - Being a mage player, some people are **** (homophobic slur removed), they go round and disarm mages because they think it's funny, and because most servers these days have a trash collection system, anything dropped is destroyed.
2 - I play Wizards and I hate it when people disarm me because they think it's funny, I have to reset my whole spell book and that can take a long time.
3 - Lamers who can't build good shit will Disarm you, steal your staff/dagger and save their characters.
Luckily I usually have other Mage friends there I can charge spam the assailant with.
