Guild Wars 2

Hey i just wanted to get some opinions on this.
Iam running the build on metabattle for the raids but iam not really satisfied with the runes they are suggesting. Is it really worth taking scholar runes for a melee class?
I once paid attention to my health bar and if iam honest i dont think its over 90% the majority of time.
Maybe its more beneficial to take the strength runes for the 5% dmg increase and the might duration?

Use rune of strench if its hard to keep ur HP above 90%
