i dont know if this will help, but someone gave me a rotation , hope this may help

solo - lance charge - blood of the dragon - jump - mirage dive - true thrust - disembowel - chaos thrust - fang and claw - wheeling thrust - true thrust - vorpal thrust - full thrust - wheeling thrust - fang and claw - spineshatter dive.

group - battle lltany - dragon sight ( another dps) - lance charge - blood of the dragon - jump - mirage dive - true thrust - disembowel - chaos thrust - fang and claw - wheeling thrust - vorpal thrust - full thrust - fang and claw - spine shatter dive.

mobs - lance charge - dragon fire dive - jump - mirage dive - repete this combo till jumpcools down again. doomspike - sonic thrust- coerthan torment - once jump has cooled down, jump - mirage dive - geirskogal - nastrond.

go back to repeteing doomspike combo until nastrond cools down, should get 3 off when life of the drogon proc's after geirskogal.

i am not sure how this works , i have not tested it yet. if there is an easier one maybe someone will post .
