The math is all wrong, war has the advantage in every salvage fight for the times they have the boss because They have the most cds and if your doing savage your tank stance uptime should be lower that 5%. If it's more than that you should consider just staying in 1 and 2 since they aren't really savage to learn how to tank properly at that level. if your a way your only in it for 1 gcd because all your doing is tomohawk>equilibrium>deliverance
Another issue I see is that you appear to be actually solo tanking this and never swapping with your co tank, don't do that. If you co tank wants to be a bum kick him and find a decent one or leave.
