If you are boosting others, aka being severely overleveled or overgeared, I would consider paying for it. But if you're of equal level you should just suck it up; if I'm a hunter I don't expect others to pay for my ammo either.
I'm going to level my warrior alt enough for Deadmines and WC and see how difficult it is to find a group if I charge for tanking.
Please post results, I'm genuinely curious :)
Somebody paid me 1G last night after running scarlet monastery like 5 times in a row. I didn't ask for it, I just said I was done for the night and the dude chased me down, tossed me 1G 'for repairs and stuff', and then hearthed out.
I'm still not going to ask for money for tanking going forward.
I’ve had a mage demand money during the dungeon because they kept dying when they opened with Blizzard before the tank even attacked.
Just laugh, write down their name and remove them.
Unless you’re “boosting” people the charge a fee is ridiculous to me.
