Some players just insist on healers to just afk between heals, I don't even know why.

During SB when I leveled AST I got into Bardam's Mettle. The tank was VERY undergeared, used no defense CDs and pulled everything. The only damage I was able to do was my DoT while the tank was pulling. After that even spam-healing them didn't help. After the wipe I politely asked them if they could use CDs, they just replied in broken English "you heal, no dps", their DPS friend agreed to that. They admitted they didn't use them because I did dps and that they will play normally if I don't. I asked them if they wanted healers to just stand around and wait for their HP to drop when there's nothing to heal. While I was typing he pulled all again. I even tried to get after them to heal again, but we wiped again of course and afterwards I was kicked. So... people like that definitely exist unfortunately.
