I had a great idea! How about the integrated parser saves the general player base the trouble of harassing individuals who obstinately refuse to learn their class, by having integrated mockery? For example, if you're pulling 250 in Ex Bismarck, it'd flash messages on your screen like "yaaar, you couldn't spear a goldfish with that, l2p loldrg", or "sorry, your class requires skill now like the others!" to bards. So there'd be class-based insults and general ones such as "go back to normal".

Also, if you plant yourself in a savage alex party and pull less than 400 as a dps role, angry red letters declaring "WGHRHGKAFAHGALGHT!!!!" in massive font size scroll slowly across your screen as your character is gradually bumped down to level 59.00 as punishment.
