At the point that you no longer run out of mana.
If you have low crit (thus, low Imp. Water Shield procs), if you don't expect replenishment in any form, then the number you need will be higher.I
have between 412 and 540 mp5 (Based on Solace of the Defeated
procs). With replenishment, with BoW/Mana Spring, with Kings, with Imp. Water Shield procs (with ~50% crit rating raid buffed), I just don't run out of mana.
I don't intentionally go for mp5 values. I put a Haste/mp5 gem in my helm to activate my meta, but nothing other than that.
and yes, Ele shoulders (and helm) may be better than your resto shoulders (and helm). Only pick one of them though, so you can keep Resto 4pc bonus. All the other Ele t9 pieces have hit on them, so they're no good for you.
Use the wowhead comparison tool for shoulders
In both cases, they have the same SP and Int. They have the same socket bonuses (But the ele helm has a yellow socket, instead of resto's helm's blue socket).
In both cases, the Resto piece has mp5, and the Ele piece has greater Crit and Haste.
If you don't need mp5, then obviously Ele pieces are superior.
Use the comparison tool to see which pair would be superior for you here
Resto helm + Ele Shoulders will give a bit more Mp5 and a good chunk more Crit, but Ele helm + resto shoulders will give you 2x more Haste, and a yellow socket (which is the desired color).
@LRPatterson, you're in ele spec and I'm assuming ele gear (Judging by your Totem).
