I think I will wear LA while I level up Alt with points. I figure between Alt & Conj, I should be fine. LA will allow me to be quieter when sneaking around until I feel more comfortable wearing robes & casting spells. So, I am looking at, for level points: Archery, 1H, Sneak, Illusion, Conjuration & Alteration, with points being dumped into Health & Magicka at a rate of 2 to 1, so, at level 6 I will have put points 4 times on Health, and 2 times into Magicka. I won't need to carry much, except for loot, so I think this will work.....
Psiberzerker, what are your thoughts???
I don't do rigid proportions for stat points, but with Magic users, you want enough Magicka to cast your spells. Especially with this type of build where Durations last long enough for your Magicka to recover. Any more than that, and you leave a little blue in your gauge which could be on the end of your Health bar, so you'll last longer. So, at first you want to be able to cast Bound Bow, then invest in Magicka when you're about to add higher level (and Casting Cost) spells, otherwise put most of it in Health by default. Light Armor is nice for magicka free protection, but then you should be able to simulcast Oakflesh with Bound Sword (As soon as you have the Novice Perks) before closing in to mop up.
Light Armor doesn't help you Sneak, it just doesn't have as much of a Noise Penalty as Heavy. Unarmored has none at all, and especially in the Boots, because the weight of your footwear is a primary Variable in the detection calculation (Meaning it's quantified before the Multipliers, and you're going for a low number.) So, whatever you chose for defence, the piece of Armor you can do best without is the boots. They don't add much protection, and they do noticably increase your odds of being detected. One way they actually do help you Sneak is with Enchantments, like Muffle (On the Shrouded, and Nightingale Boots, or Ebony Mail.)
With enough Health, and proper battle Tactics, I don't need Armor (Including Spells) at all. You'll never have enough to Tank, but this isn't that kind of Fighter, either. You just need enough to soak the occasional lucky Arrow, and stay out of the Melee for extended periods where the heavy Damage is. That's the beauty of Alteration, you can use it early on for better protection while investing in Magicka, then when you have enough health, you can save your magicka, and use your Evasion. However, your Alteration grinds up high enough to unlock the Magic Resistance, and possibly Spell Absorbtion (If you aren't summoning) perks to protect against Magic.
My point is, take stats level by level, rather than setting up a schedule like 2 health, then 1 Magicka, or whatever. If you're like pretty much any other player, you sit in the Skill menu, and surf through the constellations every level trying to figure out where this point will do you the most good. Take your time to do the same with your Stat Points, think back to since the last Level. Done a lot of Dying lately, or running away to Heal? It might be nice to have more Health. You can simulcast Bound bow, and Oakflesh, but not Stoneflesh? It time to build up some more Magicka. Keep in mind, you can wear more stat points too, if you know where to look. For instance, the Gauldur Amulet often makes the difference until I build up 3 more levels of Magicka, and then there's Savos' Amulet later in the College arc.
I usually have a Default Stat, though. If nothing else jumps right out, and say "Ooh ooh, pick me!" then put it in Health, but rather than just clicking it on reflex, remember to get some Magicka whenever you have found yourself tapping out, and having to recover. Look for higher grade Hoods, or Fortify School enchantments, and you won't need as much Magicka. I'd actually sacrifice armor, unless you need it, and be ready to replace your Robes when it looks like you're walking into a moshpit. For example, you can wear Light Armor, except Robes of Alteration, cast Ebonyflesh (And Bound Sword) then swap into Elven Armor for maximum protection in the fray...
