Let me think, so the first step to take as a rev, is that you want to watch carefully if the mesmer is running power or disenchanter. If they are power, then random dodge the first few seconds cause 90% of power mesmers use their burst on initial encounter. Wait for their blurred frenzy to end, then strike. Oh wait, they have distortion? Dodge some more, hol' up, they have jaunt and blink? Okay say goodbye cause that mf is just going to disengage and reset, GG.
