You cannot compare agro to DPS. Period. Different classes generate agro at different rates from my experience.

Was skimming over some other posts. Regarding dragoon's elusive jump. If a dragoon is having to use Elusive Jump because the tank lost agro, there are probably some larger issues at hand. Every scenario is different but some of the ones I can think of off hand are: The tank's agro generation is inadequate (yes blame the tank for not holding agro. no excuses, even on openers.), dragoon is attack the wrong target(?), main tank died and the OT hasn't generated agro. Now there are an infinite amount of different scenarios out there in which a DRG could inadvertently get agro but elusive jump isn't necessarily used for that. In fact I see the agro halving part of elusive jump more as a crutch for helping out an undergeared tank in a dungeon. In a raid scenario (especially a static group) it's most useful for positioning quickly to INCREASE DPS. Not reduce emnity.
