My warrior uses the following build, and has 480 HP (Which is the same as the base hP for level 20), and 38/40 energy (can't remember the right amount, lol)
I have all radiant insignias, and 3 attunment runes on my armour, though I couldn't find a fellblade with energy +5 within my price range. Ahh well maybe someday.
It's a good build so long as you have a monk, due to lack of decent self healing. This works well in protecting casters by crippling melee fighters that run to the back to attack monks and other casters with weak armour.
Also serves well for interupting those annoying skills you'll come across now and then if timed right, and then the 2 damaging only skills that can't be blocked (I'm aware those are the same skill, but I was limited on low cost energy sword attacks, lol.)
So after you've spammed those 4 attacks, you press what I like to call "Do it all over again" button, which recharges the skills and fills my energy bar to the top again. The 3 last skills are optional to a certain point. endure pain is good for making up HP due to the low normal amount my warrior has, boosting it to 780 instead of 480. Lions comfort can be quite good if the healers are having trouble keeping up with everyone, and spirnt to get around faster, or move to targets faster if you want.
with the rank 3 in tactics I get 95HP from Lions comfort, which isn't too bad, but wont support me. self healing could be better with "For great justice"
