To toss in my two cents on the AST sect debate, I prefer Diurnal in 4-man content since regens allow me more DPS uptime. 8-man content, though, I strongly prefer Nocturnal sect. So I jump at every opportunity to be in Noct sect. I prefer the mitigation aspect of Noct in 8-man content compared to supplying regens. Plus, if you have a WHM, more than likely they will be Medica II happy, so no need for double regens in most normal 8-man content (all that overheal too...).
Story time: Leveling up SCH, and I'll be honest, I was a little iffy about tanks doing large pulls just because it's been so long since I've touched the job, but I'm doing fairly well, so I feel happy. Excog is probably my favorite new skill. So incredibly useful and I use it basically on-cooldown for most pulls so I can DPS as much as possible.
It is mildly depressing to see my crystal ball telling me I'm pulling more damage on SCH in Shisui than a BLM though. Not sure what was going on there. >.>
