Well to be honest if you fly into anything "blind" you should expect to wipe when going up against content you KNOW is going to be different, or difficult. I'm not saying that your lack of research was at fault, nor am I saying that your a bad tank for not adapting. If you had stated that you were new I believe someone in the party should have informed you about what you should be doing, or what not to do. As far as Ninja pulling King Behemoth... well lag will be lag and flamers will be flamers.

I can't speak on the behalf of other players, "robots", but I would just chalk it up to getting into a lousy group that wasn't willing to take 15 min out of their grind to help a new tank. It's sad but it happens.

and yes, I have experienced lag while in Crystal Tower, but with 24 People in a single instance that's bound to happen, in my opinion.

Hope this helps. Keep the faith.
