If you're curious about my build go here:
Since Sacrifice damage is HP/Vit dependent, it seems wise to focus on Sacrifice skill for PVP/GVG in Episode 5. You also have the bonus of not worrying about dex, so you can pump Agi/Str. Note that this may not be the case in WOE/WOC/6v6 where you have to compromise some damage for utility/def skills.
Episode 5's damage nerf also improves the effectivity of Battle Chant. Imagine if this was paired with Tenacity 4 equips and lots of pots... GG
