I am going to be mostly aedric spear specced, for some reason i originally was going to go medium armor, but kind of realized I should go either heavy or light.. light seems weird but it really does seem to have the most benefit.

In a real fight, in Cyrodiil - where blows are flying to You every second - it seems to me, the armor does not have any value. When someone attacking, first - in fact , he are win.
1,2 seconds - and You're dead flesh. You will not have time to understand, what happened .
I saw it, in Cyrodiil MMO, when we stormed the castle )).
  In this game, is a kind of attack, one stroke lowering Your armor by 8000 points. That's all. Consider, You're naked.

Choose light armor and use stealth as possible))

Thanks Hrothbern for the advice, it seems reasonable but for the fact that my Dark Elf really loves her robes...Ha Ha. And she's done fine with them, considering she likes to cook and enchant. But spending skills points on Spell Resistance still doesn't make any sense, since there are only two levels of that passive available. And the first one actually reduces the spell resistance, as my numbers show. Unless I am missing something -- why is this option even there if it has the effect of seriously lowering spell resistance? I guess i would like for it to somehow make some sense, because it has me not trusting spending skill points in these passives. It seems a lot of the old benefits of mages wearing light armor are gone, and it is really only a detriment.

I get your point about the magicka cost reduction, though I'm not sure I want to spend three more skill points to test it out...considering what happened with the spell resistance thing... Don't you think they should have scaled these 'benefits' so LA could at least equal the heavy armor spell resistance? Not physical, just magical.

Just not making sense to me. But then many of the passive skills seem way too low to be of any noticeable benefit. I gotta say, though I do very much like a lot of things about ESO, there's a lot wrong with the skill lines, imho. There needs to be a third weapon bar at some point for example, or what's the use of having so many spells -- you can't fit even a small number of them on two weapon bars. And the passives for the most part seem, as I mentioned, pointless.

Cheers

The benefits of the Armor line passives become more and more important as your character gets a higher level.
Following link to a poll of characters that completed the extremely difficult Veteran Maelstrom Arena shows that Light Armor is very powerfull indeed in Endgame:

At lower level (in PVE) you can "play as you please".
I leveled with my current Nord Tank in 6 Heavy Armor and used the Helmet slot to develop first Light Armor and then Medium Armor. Because you can configure that you do not see your Helmet, I always had the looks of full Heavy Armor.
And ofc it took much more time than needed to level LA & MA.
But what the heck.... My looks were of a hardy rugged Nord

You say: "Don't you think they should have scaled these 'benefits' so LA could at least equal the heavy armor spell resistance? Not physical, just magical."

Well that was the choice of ZOS, and it is a usual choice.
But I would myself have favored that LA would have max Spell Resistance, MA max Physical Resistance and HA a hybrid with max both Resistances (If Reinforced traits are used etc)
I would also have favored that LA gets 3% Magicka cost reduction, MA 3% Stamina cost reduction and HA 1.5% of both. Same principle for Regenerations of Mag & Stam.
LA passives for more Magicka Damage / Heal. MA passives for more Stamina Damage / mobility. HA passives for more Damage mitigation (block costs / Break free) / higher Health / Received Healing.
etc.
Tweaked in such a way that in Endgame no more than 50% of the characters favors an Armor type and no less than 20%.

But what we have is now a given, besides some small tweaking that still takes place, and it has resulted in a for me wonderfull nice game

The small amount of slots available for so many abilities forces you to make choices. Has also her charm !
Anyway, I guess that will never change as well.

Enjoy your robed Dark Elf

At lower level you may use what you want, but maybe not all decisions are that clever for so called endgame.

In my opinion you should wear at least one piece of each armor type while leveling to level all three armor skill lines. At lvl 50 / V1 you should have maxed at least the armor type you wore the most pieces, the others should be well in the high thirties or fourties.

It's the best method if you do not know exactly what type of templar build/role you will play at max lvl or you are at max lvl but suddenly you decide to try another build/role. It's no fun if you want to play a tank right now, but you just leveled the Light Armor and/or medium Armor skill line. The passives (where you can't put skill points into now, because you lack the skill level) make the difference.

For leveling...you are a templar...you have the best skill available to grind through loads of quest mobs and soloing world bosses -> Puncturing Sweep (the magicka morph). It inflicts front AE damage, heals yourself and knocks back (which interrupts). So I would maybe suggest wear some light armor pieces for enough magicka to fire that spear skill.
