While researching player opinions on mod 16, I came across someone complaining that clerics were now just a class that stands in a corner somewhere. This sounded like an odd complaint, but I'm starting to see where it came from.
The problem is that divinity has turned into a simple resource pool for encounter powers, and one that drains extremely quickly at that. It takes less than half a dozen attacks for me to run out, and then I'm basically down to at-wills.
This wouldn't be so bad if using at-wills helped to regenerate divinity, as you could then weave back and forth between using them and encounters. But no, you're supposed to stand still and pray in combat to regenerate divinity, and it takes a while to boot.
The idea of a cleric pausing in combat to pray may have made sense in Everquest back in 1999, but in an MMO with action combat in 2019 it's absolute madness and makes you feel like a right muppet, especially when you have to keep interrupting your prayers to dodge out of telegraphs, all the while contributing nothing to the fight.
