The difference between raid and group isn't that big (misunderstand me right - I'm not saying they're supposed to be the same). It's simply that I underestimated the burst dps a ranger is capable of. From a Paladin's POV, who has virtually no burst dps, the DPS difference on a raid mob and a group mob (given the same buffs, etc) is roughly 10-15%.
Had no idea rangers could woop out that much burst dps in comparison to their regular dps. They seem to be only bested by zerkers (and barely that) when speaking relatively; a zerker would go from roughly 1k sustained to 2.5k burst (loose numbers, depends on length of burst, etc). That's a 2.5 ratio, in comparison to the 2.3 ratio the ranger has (using the 1400:600 numbers, again, loosely as I assume they're not the same player).
I confess myself surprised!
