Here are some conditionals I consider special.

moving
We can check in a macro if our follow is broken.

ready
We can check if spell is off cooldown, no more castsequence hangs

have (also known and level)
I don't know what I'd use it for, but you can make class macros in isboxer that work for any level if you can check for items.

So yeah I would try this, bet its most useful for PvP teams.
