I am fine with it. It can be a little wonky at times, when people are running around, but 90% of the time, it's not even a bother. Especially since it's off the global. As for your macros...

/cast [nomod] Intercept; [mod @
mouseover,help] [mod @
Focus] [mod] Intercept
That's all I use. Pretty straightforward. I usually have my co-tank or my melee set as my focus, depending on the fight. If it's a fight where there's periods of my co-tank not being able to be next to me, I set it to my melee. I then just mouseover the big bear butt standing next to me when he's available.
