We were arguing at top tier levels. Metawake off is one of the key ones. And even if they're not hindering you, so that you won't die. You'll never kill them if you can't get their metawake off. Every top tier fight as a Moondancer will use some form of sleeplock. Generally for SD's too, but with their numerous advantages they have more freedom.

Wow interesting discussion now...

Ok I decided I think I will have to get the rune, if for nothing else I can make a perma jewelry...

Although I have some RP for it already mostly worked up.
