Is a Support/Healer Mage build efficient?

I have a few questions:

Energy Manipulation – Increases your chance to score a critical hit with spells
Does this work with Rejuvenate and will heal in crits as well?

Spell Mastery – Increases the damage of all spells
Does this work with Rejuvenate and will increase the heals from the spell?

I was thinking along the lines of:

LVL 1-40

5 Rejuvenate
5 Magnetic Shield
5 Artificer
5 Channeler
5 Energize
5 Spell Mastery (if the theory works)
4 Blast (to push the enemies away if they get too close, thoughts?)
5 Energy Manipulation (if the theory works)

Stat wise, what do you guys think? I am not looking to do much on damage but I want to be able to hold my ground if the team falls or spilts apart, I know rejuvenate does not heal everybody on the screen, it has a certain radius (atleast from what I can see, working on one now and I am lvl 6). So I am thinking pure energy build for the MP.

Gear Wise, I want to have as much MP as I can handle, so gear with +## MP and ##% MP Regen. Thoughts?
Also would like thoughts and opinions on the (+# to skills and spells mastery) stat. Will this benefit towards rejuvenate and energize?

For the staff, does it matter what element I use on my staff? Right now my staff has ice on it and I like the concept of how it slows the enemy down a bit, or is that just my imagination? lol

So this post is for any Mage vets out there that can shed some light on this. Again, I want to go full support and be the guy that keeps the team alive, have the team constantly spitting out spells, and rarely does the team have to use potions to keep themselves alive.

From playing the Goblin Lair and beating the Goblin King last night with 2 other mages and 1 warrior, I was the only one hanging back throwing range energy balls (default attack) and casting rejuvenate when needed, nobody used any potions and it felt good to be the supporter.

heals do not crit.

But mastery does increase spell potency.

Gear: (stats in this order) Mp regen, Mp, energy, Consitution/Hp
Pure energy is fine. If you dont mind the fact that some enemies will later 1 hit kill you.

Just remember that enemy strength is stacked upon the amount of players. Having an attack skill will help. (blast or meteor work very well)

Note: Freezing aura is good when you need to revive players. That or run away.

Staff...lol there really isnt much to it. Lightning is the strongest, ice the weakest. I've never seen the ice slow enemies, but i never tested it by itself.

I have a similar mage. Its the Restoration Mage post. I'm a one to two hit kill but once something that isn't a boss touches me once, I usually don't die and I stun them immediately. Its not great for fighting through the gates and the queen but its great for moving through most other levels. I just created a mage I'm calling a restoration/damage mage. I will post it soon.

Heya bro, im building a similiar mage also. our first mage was the basic dmg dealer witht he hard hitting AoE spells maxed. but now im working on diff approach on the mage. someone made a seperate thread about it. but couldnt find out how ot reply in that one. my mage is restoration, (only 1 pt, to keep its mana cost low) so far. with maxed freeze aura, shock, then all passive skills. was thinkin of adding the fairy blood too. whats it a debate. my goal is to be a pure support mage. im tryna have as little energy as possible with maximum endurance for survival. so far ive found myself ahead of the warriors, wish every one would use invorgating aura., ive reach a point with regen rate that i can spam shock/heal like atleast 25-30 times ina row without pausing. the goal is to never stop casting, whether im static shocking their armor off or giving hps to the warrior. once i finally hit 75 i may attempt using a shield/str gear, but have decided on (lowest engery/ highest endurance route) just fr the benefit of all the MPregen from mage items. well i dont get 1-2 hitted im still real squishy now that ive started legendary mode. i was wondering if maybe i could get str gear that rivals the energy gear in MP regen, then yea i would instantly opt to using str gear 4sure. plus when holding a weapon as a mage i wouldnt swing much. it would only be for its bonus's like MP/HP after kill, or MP regen+ the block ratio of the shield" ive seen 2 handed weapons with mp regen.. do 1 handed maces with mp regen exist? for those who played D2 it would be like getting a StormShield for ur sorceror.

jan 10, 2013 *EDIT*

hey guys here to update on my build. I havnt even gotten him to 75 yet. instead i have been using my 75 MF rogue to attempt and hunt all his gear first. the stats are as following,
STR gear;
Dual regen , possibly just MP.
+endurance
+skill and spell damage
+block or dodge %
as possible make do with stat + energy insted of HP regen or dodge/block

couple questions I'd like to ask anyone who see's this.
(i know necropolis is best spot for MFin rogue gear. is that same for str gear?)
and has anyone seen the maces i mentiond in final line of first post. mp/hp after kill and or MP regen on a 1 handed mace or any str only requiremnt weapons

Heya guys I wanted to add my 2 cents on the staff info, no elemental damage is stronger than the other, u could have a lvl 74 staff of any element and wont do more dmg, possibly the ice one would slow em down for s split second longer but i doubt it.
