Minkster said:So you need a Paladin in every party? so they swapped needing a Cleric with needing a paladin so you won't die if you run out of surges hmm Okay.
Why *shouldn't* you die if you're out of surges?
Given how many things can trigger a heal, healing has to be controlled somehow. Surges seem to be that mechanism. Once you're out of reserves of "Get up and go", you have to rest. The paladin has the ability to channel some of his divine might into you even after your own will has faltered, but this drains *him*.
Assuming early interpretations are correct and all healing consumes a surge (yours or someone elses), the game is *better* balanced than 3x (can't believe I'm saying that), because you can't benefit from a wagonload of potions or a quiver of CLW wands. There's only so much healing you can get per day, total, and that's that. (A potion as something which triggers a surge, not something which contains magical heal juice, makes sense to me.)
