Secondary Runes

I am a W/Mo, can i use Monk runes?

i think so im not to sure

No. you can only use Runes of your primary profession.

Thus a W/Mo can only use Warrior runes..
While a Mo/W could only use Monk runes..
etc

o damn how lame

Well it makes sense.. I mean, if you have a monk Sup healing on a W/Mo, then change your secondary to.. Necro. What happens to your rune? :P

Runes go with the armor only. You can only wear Warrior armor, thus you can only use Warrior runes. Makes sense to me.
