Cooldown pairings

[Canadane]

Other than Raw Int. + Awareness, none. It's not often advised to stack multiple defensive cooldowns.

Living dead with Convalescence I suppose. Even then, its only if you happen to have Con available at the time of LD. You should be using Con throughout the fight. Raw Int + Awareness is the big one. Don't do Dark Dance and Blood Price. Although its not really the same, try and used weaker defensive cooldowns when you can Inner Beast a big hit - bigger cooldowns when you cant. Canadane is pretty spot on though, stacking def cooldowns is generally avoided as a rule.

Conva and ToB? How about foresight, that has to be paired to make that dinky little thing count for something. Stacking BB, vengeance, and berserk makes for AWESOME self healing and deeps when you're downing a large pull in dungeons, and that's not even counting the inevitable decimate and overpower spam. Cooldowns can be paired just fine to get a good amount of synergy, especially on WAR. "not often advised"? get out of here!
