Gear makes a huge difference. I stopped paying attention to Niley's posts in this thread after he asserted otherwise.

This is far from trivial for any team. I don't run a shaman team so I can only speak to my fivesome, but its tough.

By comparison, I ran Gundrak today after gearing up my team on the normal ToC and the handful of heroic drops I've picked up from killing the first set of bosses and Eadric (the one time I drew him). Gundrak was on farm mode for me before, but after upgrading a bunch of lvl 200 purples from ToC normal, I didn't even blow bloodlust. Was in and out of Gundrak in 45 minutes and barely had to med.

I've run that instance probably 40 times so my "skill" was no different. However, my tank is now 31k HP buffed compared to 25k prior to gearing up in ToC.

Yeah, gear makes no difference. /cough
