which rune to use

i have a helm i want to put one of these runes on but i am trying to decide which one would help more often:
1. recovery: daze and deep wound
2. restoration: bleeding crippled
3. clarity: blind and weakness
4. purity: disease and poison

if it helps im a w/mo and want what might benefit me the most. does bleeding and crippled affect me more than disease and poison etc....

what do you think?

blind and weakness. Thoes are a warriors worst fears. Btw i suggest you put your weapon rune on your hat, so you can switch it around and put the other rune elsewhere on your armour.

get the clarity, but dont put it on your headgear, thats where your weapon rune goes.

I would also say clarity. Just so you know you want the weapon rune on the hat, like others have said. You also want things you'll rarely switch out, like a vigor rune on the chest and legs. Everything else goes on the gloves and boots, because those require less materials. Also, in PvE any of those runes aren't going to help very much because conditions are randomly placed on professions and many areas are never going to have either condition. It might be useful to switch in if you know there's going to be a lot of blind or weakness in an area, but generally an attunement or vitae is better, in PvE. In PvP ignore what I said.

I would personally recommend going with a different rune, and just bringing some form of condition removal:

Mending Touch, Plague Touch, etc...
