Honestly, as much as it sucks, you shouldn't have been pulling without asking, especially since the group said to wait. You also knew that you were with a pre-made, so you really should have been asking, or just let the other tank pull.

Asking in alliance chat if everyone is ready is an easy thing to do, and honestly every group should be doing that before a pull.

As for the guy saying that this was abuse of VTK...they can report the OP for harassment, since pulling before people are ready can be considered it...if the group you're with wasn't ready and you pull even though they said not to...
