Generally I do goring blade, (popping FoF right before), rage of halone combo, drop shield oath, do RA, reapply goring blade, req right before FoF ends, and spam holy spirit until oom. (then reapply goring blade/etc) Rage of halone's enmity generation in shield oath is not to be underestimated.

I will not claim my rotation is optimal or anything but it nets me a huge enmity boost at the beginning and generally unless I have big **** dps who don't use enmity reducers, I will not have to go back into shield at all.
