Plenty of us do try to give advice, like others have already expressed. It gets annoying when people either can't be bothered to listen or get offended. Even just the other week, I had to tell a tank to use cooldowns in Rabanastre no less than five times? Did she? Yes. She used them all at once and cried how they weren't available. She even used Hallowed Ground as the off tank. When I lost patience and asked yet again for CDs, she flat out said "NO!" And got huffy after I asked the tanks in the other alliances to Provoke from her. What happened? She fought them for aggro by staying in Shield, ate a tank buster with no CDs and died. We wound up having to kick her from how much of an nuisance it became to babysit healing her.

And all this drama became from both myself and my co-healer asking politely for her to do her job.
