For reference. My opening rotation varies.
For seph ex with a whm or well geared drg my opener goes
Sheltron-shieldlob-FoF - FB(sc)-SB(shield swipe) RH(spirits within)-FB-RB-GB-FB-SB-RH.

That usually nets me enough burst emnity to use royal authority more liberally. My rotation when shadewalked/don't have to worry about high Ilvl peeps starts with GB combo into rage and royal before FoF turns off. Andy thing wrong with that or am I just gonna have to deal with it for now?
