If I'm a 2 handed light armor warrior, Do I want to aim @ health or stam? I'll have the 25% stam regen perk from light armor eventually, but I'm confused to if I need stam or health or what?

would like to know as well

Both...you need health to take damage, and you need stamina to deal damage, the more damage you deal = the less damage you take because the enemy will be dead quicker, So just spend 1 level on healtht he next on stamina and so on..that's what I'm doing and I can kill frost trolls with ease at lvl 15 with a sword/shield and using fire breath

Health no contest IMO.

Take respite in restoration if you need more stam.

Aim for both with a bit of favoring on the Health. I think I did health the first five times I leveled, then I started alrternating between Stam and health every level or depeneding on how I felt.

Its actually a plus to be a Warrior in this game becuase we don't have to worry about Leveling Magikca at all lol. Haven't touched it.

Stamina is quite important, actually. Many combat techniques, such as blocking and power attacks, rely on it.
Also, the higher it is, the faster it regenerates. 5% Max Stamina per second.

Additionally:
Carry Weight capacity = 250 + Stamina/2
The higher your Stamina, the more loot you can haul.
In general, I'll use 3 Stamina to 2 Health.

Hope that helps.

i am a light armored 2h warrior and i focus more on stam. your POWER attacks are your most useful attack (there's multiple kinds) and those take a lot of stamina.
also i find on tough mobs like dragons that the best shout to use is the FASTER ATTACK one! it lets you get more of those power attacks in while the dragon is on the ground. this shout's good for multiple enemies too since your dmg output is faster and since there's more enemies you want to kill them quicker!

Health, if you're going with Light Armour then 1) you don't need extra carry weight for your gear and 2) you're going to need health make up for the lack of protection from Light as compared to heavy.
