All I know is, I'm not going to go back to any version of the rules where my only choices are having magical healing or spending weeks in bed.
No more "somebody's gotta play the cleric." No more convenient cleric NPCs who follow the party around dispensing heals. No more Camelbaks full of healing potions and quivers full of CLW wands. I'm done with clumsy workarounds, thanks.
Actually, 3rd edition got rid of the "somebodies got to play the cleric" with the invention of domains and spontaneous healing. You could design your cleric a multitude of ways and as long as he was good or neutral, he could heal.
What 5th edition should have done was use the specialty clerics from 2nd edition, spotaneous healing from 3rd, and Turm Undead as a feat from Pathfinder.
