Not really a new player but a very casual one, been playing since U9. Anyhow, hadn't played really for 5 - 6 months due to work.
So, as the title says - where did all the HP go?
My Lvl22 Dark Monk/Fighter/Pally pajama tank went from 800 + HP to around 590ish after respeccing Enhancements.
In good news department, to see how build was with new enhancements I could still solo EH Devil Assault, which just soloing it in the first place was a super big achievement for me, so the HP lost didn't really seem to affect me too much.
Long story short I was planning pally for my next life 12 HotD 8 dark monk or something or other - wasn't quite sure how to approach it now with new enhancements since Hunter of the Dead and Dark monk no longer exist.
