Had a similiar situation but no one was running. Some Warrior Guy brought his farming build into the random arenas. I dunno if he did that on accident or on purpose. Our whole team died, except for that warrior. The other team consisted of 3 warriors and one monk.
That warrior had Live Vicariously, Vigorous Spirit, Healing Hands, Healing Breeze, some kind of Stance (Bonettis Defense i guess) and cyclone axe. lol.
They kept on bashing and bashing and bashing. They did hurt him, but for real low damage and everytime he fired up cyclone axe he was fully healed again.
Just imagine the picture 3 warrior and one monk attacking a single target and not being able to kill it as no one brought interrupts. After about 15 minutes with no scratch of health gone he finally gave up
Nice video, and I see that one of your team amtes already left! That happened to me, but I was on the opposite side of it. Lucky for my team, the runner using rez didn't count on my ranegr using disrupting shot and storm chaser
