Macro theorycrafting for Rift

So I was reading this, looking for ideas and I already discovered

Code:

#show OneMinuteDebuff cast OneMinuteDebuff wait 55 /p OneMinuteDebuff is wearing off, re-cast it now!!

to remind myself to redebuff bosses (I've recently been putting more points in the warden tree as I level because I am hoping that the second, lifebloom-style, stacking HOT at 16 points will eliminate most wiping in dungeons, but these healing points mean that my damage per toon relative to bosses is a little slower than before so I think I'll often have time to reapply the 60 second debuff when I think of it).

EDIT: The above tip will not work if you have another macro in your spam. As the macro is still "running" during the 55 seconds between the cast and the /say, you will get the error "can only run one macro at a time" when you try to use your dps or aoe macros. Live and learn, but this makes this essentially useless. I can probably do something similar with ISboxer if I really want to.

The other example that I find intriguing is that in rift you can actually cast at raid marks.

You mark using the

Code:

mark 1

command and then you cast at it with

Code:

cast@ mark 1

presumably if the mark doesn't exist then the cast doesn't happen, I was trying to think of times this could be useful, perhaps to mark a group member momentarily for heavy heals that would interrupt all the normal dps rotations, or obviously CC. Ideas?
