"The fighter is limited by his items. As he progresses, he learns to wield his weapons better, and eventually has very large bonuses to hit and can have great damage by comparison to other martial characters. However, no swing of his sword will ever create another plane of existence. And that, more or less, is the difference."
Fighter: "I can kill a guy in one turn."
Cleric: "I can kill a guy in half a turn."
Wizard: "I can kill a guy before my turn."
Bard: "I can get three idiots to kill guys for me."
Well that seems reasonable, though I can't say I've ever had a D&D discussion (or, come to think of it, any other discussion), end in a screaming match. Still, I had this horrible mental image of the show Cops breaking up a D&D game, chasing a pasty-skinned, overweight guy with an unkempt beard and no shirt down the street while he screams "Expeditious Retreat!"
that is... demented and brilliant. I heartily approve.
PC (Krusk): Oh. Ummm, interesting. Since I'm not raging, the best I can do is a 32. Here's hoping for a natural 20! [Rolls die. Does not roll a natural 20. Throws die out of room. Crushes favorite pencil in hand. Breaks clipboard in half. Casts character sheet to the ground and stomps on it.] That ALWAYS happen to Krusk!
