Not all heals are 10 rounds, just the most potent ones are. In fact, there is a 2nd circle spell called 'Mend' that heals 2d4 + (priest's circle) in one round. -Thus, it's a minimum of 4-10.

I've just limited the number of combat heals. However, priests have more options to get the party back to full after combat is done.

It's kinda like Little Caesar's Hot-n-Now. If you want it now, it's gonna be pepperoni. If you've got a little bit of time, you can get more toppings.
