1. Rake for 1 combo point also stunning
3. 1 Shred for a second Combo point
2. Savage Roar for 12 seconds
3. Burst Macro for Berserk - Troll racial berserking - Tiger's Fury
4. Rip and Tear giving full rip and rake damage and time with 75% increased damage using 0 combo points so that's full DoTs plus probably 5-6 seconds of savage roar left at least.
5. Generally throw in an Enraged Maim now - After this step it's changes in any situation - You'll be sat on nearly full energy due to Tiger's Fury so either go to town on the kill target or which to other target
6. Use the next 3 combo points on a Savage Roar - 3 will normally pop a free Regrowth
7. Don't use the regrowth until 4 combo points - Regrowth for bloodtalons, Rake for 5th combo then Rip.
