Thanks Ualaa for all the above replies. As usual, you are correct on every point and have done a nice job explaining things.

Stingc, to be honest I haven't messed with the Prot Warrior macros very much. The only thing I really use the single attack on is when I'm using him to tank the 3D Sarth. The macro works well enough to keep threat even when three of my DPS are putting out over 10K damage, so it's got to be pretty good

As to it getting hung over the long hall, I guess that's possible - I never use that macro for more than a minute at a time (if Sarth is up for more than a minute, it is a wipe), so I haven't tested over the long term. I'm also out of town visiting family so can't test it for the next five days.

Then again, in the PM you sent me this morning, it looks like your 2 Step setup isn't quite correct, so that could be the problem as well. Let's work it from two angles - I'll send you a reply to try to get your 2 Step fixed, and if you find something in your testing to optimize the tank macro, just post it here.
