I agree, if someone is kicked out the DF should not put them again in the same party.

I run once as a Paladin in Tam Tara Deepcroft (Normal), and the Whitemage casted 'protect' on both of us while the DPS were new and they had the CS. She never casted protect again.

When I pulled mobs the DPSs were doing their job while my HP was getting lower and lower her Character pose changed the "idle" pose arms/hands behind her head. She cast cure when my HP was lower then 20%. I asked her to heal and cast protect, she never replied.

When time passed allowing us to kick her out she went in a flash, and got back -again?!- 10 seconds later (I figured out she was doing this duty for her Book) saying "Orly?" she came by and did the same thing, I asked her again:
Me: "can you please protect the guys and cure more frequent?",
she replied: "R u see urself dying?"
Me: "with all my respect you are no better then a healing bot"
She said: "plz don't waste time and GO"
Me: "Sure, I'll Go. Sorry guys you were good DPSs"

I quit the duty, I am a whitemage but that person is a shame for being a healer.. God help the people who run with her.
