Thanks all for the advice.

Got my setup working last night - not attempted anything more than the training dummies but got all the controls about right for the 4x DK. I've chosen Blood for now as it seems to be simple and survivable, I've noticed when I've seen boxers around they normally run Unholy (any advice would be brill!) - for levelling I'm not investing enough to worry about respeccing down the line.

One question - I have a 110 HPally (only around 850 iLvL) and my new 4x 100 DK's.

Should I quest as a 5-box during levelling 100-110 or just level as a 4?
