Dear staby dave, let me explain what I meant:
DPS is a misleading term that makes people think that some weapon are more effective then others. In a "real" rpg, where everything is calculated and everything is "predetermined", DPS as a term works fine. But how would you use that in cRPG? Just because you CAN shot 1 arrow per 3 seconds dealing XX amount of dmg, does not mean that you de facto deal that damage. Most archers hit very few arrows where I (for example) hit people with at least with 50% of my bolts, because I choice very carefully when to shoot and when not to. That's what I meant with playing proper.
In my own very special world, an xbower is a slow support char, who shoots when it matters. Of course this becomes a problem when everyone needs 2-3 bolts to go down, but it's usually solved buy shooting squishy archers instead, or simply staying alive or picking off people with low health.
