Ahh .. the Ring of Blood. One of the at time greatest quest lines.

Yep, most of us who have done this a few times recruit out-of-group help to get through the chain smoothly and at one sitting.

In my current boxing career I took my 5 shammies through the Ring of Blood at 65 with cross-faction help ON A PVP SERVER. That was a high-point of WoW for me. I came upon a Horde group battle in progress and helped them dps down all the encounters, with appropriate emotes. They stuck around afterwards to help out all my guys - they even tanked for me. Wouldn't count on cross-faction assistance, but this is one where it's better to run through the quest line twice with an outside group then to struggle through it in a solo group. Especially if you want to get the quest rewards and use them as soon as possible level-wise.
