don't look at just dps either, look at overall dmg. in 30 secs your overall dmg may be 10k and your DPS 4000, or 50k and DPS 2k. The person doing 2k dps will always, always, always be better than the 4k dps person since they did 5x as much damage in that timeframe.

Recount is kind of bad in that DPS is a misleading number, it is really "damage per second CASTING". You could cast a 2 second spell, go afk for 15 seconds, cast another 2 second spell, and the time spent casting would be 4 seconds, instead of the 19 seconds you really were "fighting".
