Dual Skills

My dual is 92 so I can't test for myself which dual skills are best for me. But I still wonder which ones will be.

At the moment I am not recieving a lot damage on sieges because I know how to avoid being hit and have macro to inform my dd's in the party when I am under attack.
So far I have taken dual passive HP. Description says it add 6% but it it actually adds 4%.
I am thinking to go all the way to lvl 4 passive HP.

Having 16% more HP it's better for the party heals and with reflect it hurts more my enemies.

What is your point of view?

i didn't really think about hp when my time came around for passive dual class skills. i just thought i need to be faster at casting. so i took cast/attack speed. for pvp the extra hp is great.
the % increase is from base hp, so it seems lower due to not being affected by buffs, and passives.
base hp being 10000 would increase by 600
this is also why i overlooked the hp...

if that is wrong, then i shall reconsider it.
