Enhancement Shaman Build Stats

Hello Everyone! I have some simple questions about stats for Enhancement builds.

For Elementalist Build should i go Mastery over Haste? (AoE and ST, or is different between thesee two?)

And for Physical Build should i go Haste over Mastery right? If this is like this, how much Haste should i get?

Sim yourself but for me its haste to ~30% then all mastery. Mastery def. Way more preferred in AoE sims too

Basically yes, for the physical build you want to prio haste (likely to 30% or so again, maybe higher its been a while since I simmed the physical build) > crit > mastery
