Will Paladins get an enmity boost as well?

Exactly, don't do anything else, regen TP and just overpower when you can. I'm pretty sure it's 60 TP every GCD (2.5s).

Nope, all recovery and DoT ticks are synchronized. They are all 3 seconds. It would take 3 ticks to regen enough TP for Overpower, so 9 seconds. One second below 4 GCDs
