I know you wrote that 2 weeks ago, but I really had to laugh here.
Look at this screenshot here:

This screenshot was taken on the day of my last tank role in RDF HC.
What you see is me standing next to my healer, waiting for his mana to refill,
while all three DPS randomly went ahead and pulled the extra boss in Stratholme.
They didn’t even bother to wait for me, let alone the healer.
My healer got mad and left.
That was the last time I tanked on this server.
And if it's not the DPS doing this, then it's a Druid or Paladin healer
who decides to start pulling more packs.
This server simply has a huge narcissism or anti-social problem,
whatever you want to call it.
