Sometimes a player with a high forge level in a weapon is matching with low lvl players, and the mission lvl becomes low lvl too and that happens... I saw that on In Shock a couple of times, I remember one in were the Konstantin had a high lvl weapon and eaten the beholder en seconds, then Kuzmann... another was myself, were I was with a bunch of low lvl and I with Mikah was doing a lot of damage to the beholder.
