I never said I expect every cleric to do nothing else than healing.
Then you implicitly expect the cleric to blow cash and wand charges on the fighter, because nothing less than doing nothing but heal will cover the entire amount of damage taken.
I only say I don't like expecting every character to bring a wand of CLW and calling anyone who doesn't an unfair player.
Whats the other option?
As long as the healer brings their own tank to stand between the monsters and them, then it's fair to demand players bring their own wand of CLW.
Most pfs groups i've seen have been pretty melee heavy. Nothing is in between the melee and the monsters, resulting in a lot of damage taken all around.
In PFS, it's not a bad idea to own a wand of CLW, because in an organized play environment, players will often find themselves in groups without a full healer, but again, it shouldn't be treated as mandatory.
Well there is infernal healing if you prefer...
