I really can't find anything particularly upsetting about SCH in its current form that wouldn't be nitpicky honestly.

I miss having more to do and maintain during downtime than Broil Spam but not to a point that I find the class less engaging to play. I miss Bane and DoT management but I've gotten real good at playing "How Low can the Tank go" before feeling at risk for their life, except when I get paper tanks which are the only times I feel fully justified burning so many CDs to keep the party going, despite how often people prefer to run outside my Sacred Soils, be too far for Whispering Dawn to hit, etc. Instead of focusing on maintaining my DoTs, I'm now just trying to optimize my healing effectiveness by monitoring my healing tools more, making sure I get Recitation/Deployments lined up for Raid damage or getting those LD DRK from collapsing; its a different form of engagement than before. My only real complaint is how negligible I've found Seraph to be as I totally forget to use her sometimes and it doesn't effect my overall experience with the class at all.

So sure, buff Seraph, but I just don't really feel like SCH is really all that bad now.
