so been checking raider io of some DH, alot use both unbound chaos and cycle of hatred now, when i pick those and sim myself then Mastery suddenly leaps ahead of Vers/haste.
it make sense since its chaos dmg, but all the guides still says go vers/haste, heck even the DH discord told me to go vers/haste still.
This is easy math,
Demon-hunter scale very bad with Mastery
For example
1 mastery will give you 1 chaos dmg
Demon-hunter scale alot better with versatility / haste
Example :
1 vers = 1% dmg increase (for all skills)
Your right, mastery is logic wise a good Stat but since we scale so very bad with pure mastery you will pick in every condition vers and haste over it.
