Sleep marking

I recently came across a macro that I really liked, but if the game developers could modify how markers are done, it would be quite a lot better. When I cast sleep on a target, I put /mk ignore which puts a marker over the one I've slept. It makes it far easier for the damage dealers and tanks to see which mobs are slept so they don't wake them.

Every mage I've showed this idea to loves it. It's pretty popular.

The problem is, the marker stays on the target even when it's awake. What would be really helpful is if the developers could make it so that the 'ignore' mark automatically goes away when the sleep status wears off.

Maybe they could make a subcommand for marks like /mk ignore <wear>, so that the very next spell cast after the /mk command, will make the mark disappear when the status disappears?

Thanks and keep up the good work!
