[SnowTroll]

The general rule governs in any case. Not just for stats, but for everything. The objective is to be interesting, have fun, and do it in a way that's not stupid, tedious, or unfun for you and for the other players. Playing something commensurate with your stats kind of falls along the same line as playing something that lines up with anything else about your character. You annoy people and make the mud stupid and unfun if you roleplay a powerful behemoth who knows everything about everything when your strength and intelligence are pitiful and two seconds into a PvP or group PvE event, your character's underperformance is obvious. Just like you annoy the mud and make things stupid and unfun if your troll barbarian from the savage lands regularly attends and butts into the mage college's debates on magical theory because the player likes to win arguments and garner attention even though his character has no business having anything to do with that event.

You're supposed to roleplay in a way that lines up with your character's background, your character's skills, and your character's everything else. So why not stats? Unless you're playing in one of those muds where the grind and the arena are treated as something entirely separate from the chatty RP scene. They exist.
