Ive been trying a new rotation lately, shame there is no 100% accurate to way to check dps though :/

After stacking up GL and adding DOTs

1. Flank: DK-TS-SP
2. Back: BS-Impulse drive x2
3. Flank: TS-SP-DK
4. Back: Impulse drive x2
etc.
Fit in DOTs whenever they run out. IMO lancers impusle drive is better than our own True strike. And I can fit two in.
Its a strange rotation to get used to at first but easy once you get used to it. Only thing Im not sure of is if it really is more DPS, maybe someone else has tried it out and can give their input.
