Your build is far away from optimal. First HA/EleA sux a bit. If you get armor with reduce chakram cost 4 or 5 and quiver with + 1.12-1.33 HR and your warrior with ressource regen skill. Pick bat and lol you got 9+ HR/s. You will be able to keep chakram forever and you have free skill and you can choose Cluster Arrow. When you see group two clusters and than spam Chakram/Razor Disk most of the elite packs just die instant on MP2. Also you nee Legacy Nat with Tactical so you can keep 60% movement speed all the time. Also keep in mind that DH with 300Ress and 200k+ dmg without SS can farm MP4-5 without any delay.
Sorry i dont find chakram optimal at all. It doesnt hit all the mobs from a big pack. Elemental arrow does hit em all cuz it paths trough the middle of the pack hiting everything twice.
And why would i care about Hatred regen? elemental arrow doesnt cost much, and clears everything in 2 / 3 hits. Also vengance fills your hatred with 1 / 2 health globes and your discipline so you can have full disc to vault to the next pack.
And as i explained in the guide, mp 4 5 is not efficient even with ppl with 200k dmg. I can clear mp4 5 at amazing speed. And even then you cant compare the 50 millon xp/hour you can do with this route..
xp and legendaries is about killing as much white mobs as possible. Speed is the key. And mp1 - 2 is just more efficient than mp4-5 no matter what your gear is.
The math has been done on several forums.
