You're very welcome! ^^ The rotation for the Super Special Regens is basically this:
Lightspeed > Synastry > Aspected Helios > Aspected Benefic > Collective Unconscious > Bole (if you were lucky enough to get one) > Time Dilation > Celestial Opposition
That offers some really nice regen ticks. Even better if the tank pops Convalescence before you get started on them. I was testing it out on a friend one day, and he went WAR, using Defiance, Convalescence, and Thrill of Battle before I got started. My regen ticks were averaging 8,000. It was glorious. XD
I much prefer Diurnal in 4-man content, just for the reason with having regens ticking on the tank (or DPS if they like AOE puddles), it allows me to spend more time in Cleric DPSing. Fo 8-man and 24-man content, I prefer to be in Nocturnal. If I had a fairy to heal for me in Noctural, I would definitely go with Noct all the way though. ;p
And it's okay. XD I only use Lightspeed if there was some sort of huge oops, and there needs to be a lot of healing to try and make the fight recoverable. I know some ASTs will use it for Gravity spam (have seen some in content, and read comments from other ASTs), but I would recommend against that, because it also lowers your DPS output by 25%.
DF story: Got out of a Sohm Al HM where the adds for the final boss spawned 4 times. o.o We wiped the first go around because the BLM didn't LB the second set of adds. I'm trying to keep the tank up (with my Super Special Regens), but some of the scorpions when they spawned decided they wanted to eat a healer for breakfast. So my casts are getting interrupted, tank goes down. I manage to Swiftcast+Raise him, and Essential Dignity myself, but it wasn't enough because the boss killed the DRG and then went straight for me. ;_; We got it the second time though. I told them if we could get the LB built back up to use it on the second pack. The tank and DRG apparently had never heard nor seen that done ever. o.o We didn't get the LB though, so we had to kill them the old fashioned way while I regened the tank.
Idk... DPS was really slow. But I didn't have my "crystal ball" with me, so I don't know just how slow. I don't think the BLM was puling their weight though. Because I at least saw the DRG using their buffs, and what looked like a decent rotation (don't know too much about 50-60 DRG though). I had more health than both the DRG and BLM on my AST so. XD But at least we got it done. ^^
