I always thought we would get good utility things like:
reraise - target is revived without weakness (as long as the whm isn't dead? to prevent too much cheese)
aoe esuna - just add raid content that throws out a lot of party wide bleeds which would only make our regens more desirable
stone apply vuln up - 1% on first hit, 3% on second consecutive hit, stacks up to 5% and lasts say 12s before the enemy gains resistance for a period of time
faith/bravery - targets physical/magic damage gets a big boost

We definitely got excellent mp management.

I didn't expect RNG procs reliant on conservatively used heal spells so that you can maybe have slightly quicker usage of OGCDs OR so you can apply graniteskin. The Lily system is painfully underwhelming.
I kind of did expect moar healz but confession stacks has to be the worst way to possibly implement this.
