Not sure if this is still an issue, but for a while I had a macro with Heavy Swing and Tomahawk macro'd so that I'd use Tomahawk if I wasn't in melee range for Heavy Swing. Problem was that often items I'd be in melee range but it'd cast Tomahawk. Needless to say this would screw up both my rotation and eat my TP.

It's personal preference, but I'd rather have a bunch of hot bars for all the abilities than have a few black box buttons, unless you have two skills that you would never use independent of one another that are off the GCD. Even if you use off GCD abilities I've noticed you can get a little lag on your GCD if you use it too late in the cooldown, but it's only something like half a second.
