best 2 of 3 for me? :Mind over Matter, Blasphemy + Enfeeble, Arctic Armour

Trying to decide between the most ideal defensive set up for my mana pool. My choices are those listed in the titel: MoM, AA, Blasph+Enfeeble

A bit about my character...
Totem build so I am in the back majority of the time.
level 75 @ 5K life
20% phys mitigation
160 mana regen/sec

I run three curses for my build. Flammability, Elemental Weakness and Vulnerability

[option 1] MoM @ 674 unreserved mana w/ AA active
[option 2] MoM @ 552 unreserved mana w/ Blasph + Enfeeble active
[option 3] AA with Blasphemy + enfeeble, no MoM... save a few points as well

I know my mana reserve is low but I do not get hit all the time, my totem bros do. My mana regen is strong enough that getting big hits periodically is fine and the pool replenishes very fast. Blashp+enfeeble is always strong but majority of the things that hit me will probably be out of range. Also this eats into one of the damage curses, though not to big of a deal. AA is only good when not moving but strong when stationary.

Thanks for your inputs.
