Cooldown pairings

[Cabalabob]

Berserk/fight or flight and bloodbath go well together. But yeah it's generally not good to pair CDs as it reduces their effectiveness, since they're multiplicative, not additive.

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.

I think you mean walking dead, using convalesce while living dead is active is kinda counter productive.
