Good Vid. Just a couple of tips though.

LOS the casters to make group them all up so you can kill them easier and quicker. Either go around a corner or use the gates, for instance the very first pull you did, just take them all back to the starting gate and open it up and go just inside the tunnel there. Once the gate close all the casters with run to you.

Also more strafing would allow you to handle bigger pulls, although as a warrior, not having cleanse and hand of freedom that might be more annoying than it's worth.

Lastly becareful where you place your followers. Even though you may have cleared an area those damn eyes of naxxramas are everywhere and the last thing you want is to take the time to make a big pull and kill everything just to realize that you followers are all dead before the xp started rolling in and they didn't get any of it.
