Reprisal stacks with Path, I have always wondered why people see this Delirium-vs-DragonKick-esque competition between the two. In practice a raid group with DRK and WAR is probably getting a lot more mileage out of Reprisal actually, as its on the boss considerably more. Yeah its gated by parry, but you uhh.. tend to parry quite a bit in a non-ReX/A4 fight. And its off GCD, not gated by a combo. Path is amazing, yeah, but in an actual raid your WAR will happily forgo using it while you keep Reprisal up 50-60% of the time. Not to mention Delirium in the absence of a MNK, DRK is the only tank that suffers -zero- loss of DPS by keeping a boss debuffed with maximum uptime.
