Hehe I went there with 10 prot paladins (ilvl range 807-819), and to be honest, the whole time felt like cheating here and there. I have one button macro set up in ISBoxer (basically: cast anything that isn't on cd) and it appears to have great aoe healing and self healing so there is no downtime at all.

I found a spot where three portals kept spawning, greaters and lessers. I kept aggroing all the portals constantly as the IWT melee teams tend to run around a bit. They're also engineers 150+ so looting have never been more fun
