I have a strict policy: 'he who whines about heals, gets no heals', which I'm also happy to apply to rude players of any description.

By all means, remind me to switch off cleric stance, or make a suggestion regarding my strategy, but you'd damn well better be polite about it.

I have been known to get cranky at Bards who don't play ballad when both healers are out of MP, though.
