I can see solo stunning. Even then, I'll idle/rest in Errant to drop the Enmity. :3
One of our recent Tia's tho, I was solo stunner most the fight, and I never pulled hate with Nashira +4 Enmity merits. I really odn't have much -enmity either, but our group is good shit. I don't have to heal much, I concentrate on Stun/Refresh/Slow/Phal and I'm good. :3
It's really all about yours and everyone's playstyle. You lag a bit? Maybe AF2 is yer thing. (You and Jud mention 5% Recast on timers, but it's got Fast Cast, too guys, don't forget! Some are a bit slower on the trigger, imo.) Low DRK skill/you want potency? Nashira<3. You want Conserve MP/Enmity-? Definitely Goliard.
EDIT: Jud made that last post, and yes. If you're a solo stunner with TTK, then fucking use Goliard. Sorry, Jud. >.> HKO, hehehehehehe.
