I have the same team - mine is 23 and have been doing SFK, the last boss is very hard. I drive from tank as well and prefer it over the shaman once you get into high dungeons and start having to do a little more than just tank and spank. Ie chasing runaways or moving the team out of AOE will be hard if you are with the shaman. Also i prefer to melee with the shaman to dps rather than lighting bolt

I would suggest when you do you videos you should show how you are using multi boxing, not sure how but i am sure you can - I assume you have 2 monitors which is why we cant see when you select your warrior to pull
