The surrounding Horde characters promptly stepped out of range of the special Storm breath and proceeded to do single ranged attacks forcing his health up. Instead of killing an enemy of 3k health, I was forced to fight one with 14k health. By myself. As they laughed and "spammed "kek." Every time his health would drop they would do another single attack, shooting the health back up.
The system seems like there are situations ripe for griefing as it stands. The opposing faction stood nothing to gain from this particular enemy once I had tagged it. Allowing them to boost its health and do nothing seems ridiculous. There does appear to be a timer built in that drops the health after a certain time of inactivity from other players unless I'm misunderstanding the mechanic. Perhaps that time needs to be drastically lowered so that people would need to actually contribute some form of damage to keep their stake?
