Magic Atunement is a bit more of a grey area on damage output. Arguably, it's the difference between casting and not casting, but for fights where there's a significant amount of mobility and distance required, I'd just say go fire! (no reason shit can't be situational in WoW too, right?)
I admit, Student of the Mind is NOT a zomfg damage increase due to the high base crit rate of arcane due to clearcasting +30% crit procs, and instant-crits from POM, but it is still a higher increase in damage than just increasing your resistances. In terms of mana recovery of SOTM versus MA, it would vary fight to fight depending on what you're getting hit with, and your gear's base spirit... Although your earlier justification really didn't put an emphasis on MA as a form of Mana regen.
Instead, I personally went with 0 Atunement, 0 Absorption, to put in 5 SOTD and a third rank over in Ice Shards to increase AoE DPS. Due to our high crit rate (as mentioned above), we can get those nice Clear casting crit buffs on blizzard, and doing an extra 33% bonus crit damage is a significant increase.
