So... I'm having a a helluva time leveling my tanks through Vault. The past four runs have ended in failure at the hands of Ser Sherbert. (I don't remember his name, don't care to). The common problem seems to be that the healer gets chained to someone and either doesn't run from the person they're chained to, or the other person doesn't run away from them, and they either get stuck in stacked aoes or run into the knights. As a tank, I can't really do anything to make the run easier, except for mitigate my damage to make it easier to heal me, but that won't stop the healer going down because of mechanics.

I need a sound strategy that I can tell people to try to ensure a clear next time. So, my question is about Holy Chain. Would it automatically break if the DPS and healers were as far as they could be from each other before it appears? Also, would it be easier to tank Ser Sherbert at the bottom of the arena to allow people more room to weave between the knights?
