Mannimarco is locking the game, at least for mages. I am at level 48, can't find any monsters brigining experience in Bangkorai, so, basically, unless my mage can defeat Mannimarco, this game is a DEAD END! Indeed, killing Mannimarco is the obliged way, the SINGLE POINT of passage, to allow progress, but that is merely IMPOSSIBLE for mages. By the way, for mages, the quest levels is totally screwed: some quests are definitively too low level, too easy, for mage, at the announced level, but some, like Mannimarco, a level 40 almost unfeasible (totally unfeasible for me) for a mage, even for a level 48 mage.
I understand that being "hard" at some place could be ok, but when it kills the game progression, that is not a "game" anymore.
