Ok. I have stability but not dual. Will try. But still doesn't solve problem when you're venturing through the wilderness. 3 minutes isn't that long. Especially when you're suprised attacked by a bear or just about anything for that matter. Re-armoring every three minutes svcks.
When you're surprised is the time to cast the spell. It's not permanent for a reason; as an alternative to armor, Alteration spells and perks have advantages and disadvantages for the sake of balance, and I think it works perfectly. Three minutes of 300 armor (or 350 with the Lord stone, plus its 25% magic resistance) is not too shabby--that's more than half the armor cap, not to mention no encumbrance whatsoever and extra perks for spell resistance and absorption!
To add to that,
unlike armor, Alteration has other combat utility. By the time I was able to paralyze foes, it was really a choice between that and Ebonyflesh; I didn't need both. Also, I don't understand how you're playing that makes it necessary for armor spells to last more than sixty seconds. Anyone who invests in magic skills should invest in Magicka growth, and I have had no trouble recasting my armor spells when necessary (especially what with the big visual flair to let you know that the duration is over).
The master perk should reduce cost of master spells by 50% AND allow for alteration skin spells of expert and lower to last until recast by the mage.
No, it shouldn't. That's ridiculous. Cast a spell
once ever and you have a permanent 300 armor rating until you "recast" (and why would you recast)? I have never heard a suggestion more gamebreaking.
I just can't dual cast at all on Xbox, say I have firebolt and I press both triggers at the same time, half the time it will result in one big firebolt but the other half it shoots one from each hand
You are definitely playing the game wrong, my friend. Consider purchasing a new controller; either that one is in disrepair or you're not too good at using it. There are controllers for sale of different sizes with different button placements and sizes. This is not a problem with Skyrim, it's a problem with you or your controller.
