The whole purpose of the monk 105 build is to get your health as low as possible, so by placing any vigor rune on your armor it is defeating the whole purpose of the build.
replace it with any other sup rune (go for the cheapest one you can find)
you can use more than one of each rune, you could for instance use 2 superior divine favor runes. you wont get the extra +3 divine favor, as only the highest bomus applies... but you still get the -75 health, which is the whole point.
Enough threads on subject. As someone pointed out, the lower the health the better, hence you don't want any vigor runes. Add on to an existing thread about a build if you have more questions/comments.
