[Mage] Haste or Mastery

[Clarkey]

I'm not looking for someone to tell me how to gear my toon as I've hit 85..
No, I've been 85 for a long while now and I'm just confusing myself with numb3rs.

I'm torn between Haste or Mastery for arena.
I've been playing Haste for a long long time but I've just reforged / ench / gemmed for Mastery, as my 3s partner requested I try it.

I've noticed damage increase compared to my hastey days but I just don't feel comfortable and I don't know why (haaalpppp)

I've always kept the target frozen as much as possible when I was hastey so it's not like my mastery points are going to waste.

As I've wrote this thread, I'm not sure what I want from you as a discussion.. I suppose, just a headcount really of what stat you magic PvPers go for and why, I'd love to read through all your opinions etc.
