umm..... why the bashing on one job of many that can pull and tank multiple mobs like this? The level of hatred for a job that has been treated like the red-headed step-child for years and has finally managed to carve a new niche for itself is just astounding.

As many have stated, you can only maintain your claim on one target. The game is intentionally designed to function that way for a reason. All unclaimed targets are fair game. Claim one, proc it, kill it. The game is designed to be played that way. If they want to debate you over the validity of such action, direct them to the games ToS.

SE has stated that monopolization IS a violation of that TOS. So.....if this REALLY is a problem for you, then you need to report it through the proper channels. Granted, they may not take immediate action. I have run into this before with someone monopolizing a target. It took an entire alliance of complaints before a GM took action.....but, the point is they DID eventually do something about it. We just had to get enough voices raising hell about this guy before anything happened.

TLDR:

There already exists several remedies to this situation. The bigger problem I see is that you chose not to take any of the appropriate actions to resolve the issue, therefore the problem persisted for you. Now you are are butt-hurt and calling for a massive nerf to one particular sector of the playerbase simply because YOU failed to do what was well within YOUR power to affect a change in the situation.
