Major and Superior Runes have a health penalty?

Wow - just saw this.....

-50 hit points if you use a Major Rune
-75 hit points if you use a Superior Rune

This seems high no? As a 17 Necro I think I have 420 hit points - using a superior rune would drop me down to 345. An almost 20% reduction in overall hit points.

Do most folks just use the minor ones to avoid this penalty - or do you guys not care and use superior runes?

Thanks!

get one sup. rune, thoes three attribute ranks can go a long way

Where did you see that?

use a superior rune of vigor to help offset that penalty
