So, I've noticed when looking at most people's leveling builds, they tend to put all points into either magicka or stamina. it mostly seems to be magicka for a couple reasons:
1. magicka skills tend to be more powerful than weapon skills, not all of them but most of them. either scaling better or having better effects.
2. stamina is used for dodging, blocking, sprinting and bashing so if you are a stamina based character whenever you use any of those combat moves you're draining the same resource bar that you use for your weapon skills. magicka based builds can use as much stamina as they want since most of their skills won't rely on it much.
3. medium armor provides stamina regeneration and that's it's only direct benefit to weapon skills (attack speed, better stealth and crit chance don't directly affect weapon skills). light armor provides magicka regeneration, reduces the cost of all magicka abilities, increases spell crit chance and reduces enemy spell resistance, all of which directly benefit magicka skills.
I would really like to build a character focused around stamina but for the most part it seems like magicka based builds are stronger. can anyone point out any significant benefit to using a stamina build? the only thing I can think of is that your normal attacks will be a bit stronger but I doubt that would make up for the extra damage/utility you could put out with magicka abilities.
