Kitting and evading sure as heck does. Blast a few spells, move back around a corner.. oh look my magicka is going up... blast some more, move some more... avoiding damage.. dealing damage.
Sorry to have to break it to you but a successful damage dealing mage on master difficulty has to keep active and put some skill into their gameplay. If it's too much for you, turn down the difficulty.
Magicka regen is pittiful in combat. What you are proposing is kinda like watching paint dry between each kill.
I wasn't aware that evading enemies with my warrior would restore my health or stamina.
Stamina regen is very good and since you only need a tiny bit for one power attack, it's not even that important.
You know how you would enchant your weapons with shock damage? Instead of doing that, you use potions to increase your destruction spell damage. Those dual-wielding BAMFs would not be half as powerful as what they are without an absorb health/shock enchantment on their weapons.
You sure? Let's compare my level 45 with 100 destruction/enchanting mage and my new level 28 with 75 smith and twohanded barbarian that put every single level up bonus in HP vs the aforementioned arch necromancer in master difficulty.
End result? My barbarian using only a crafted glass greatsword and enhanced with no additional bonuses (nothing, no pot, no enchants) using only a single +20% twohanded damage ring killed the necromancer nearly as fast as my mage that had the best enchants one can find and spent the whole fight spaming the strongest lightning spell available (ie, dual casted expert thuder spell) I can't wait to gear up my warrior even more and get more HP! I didn't even get all the damage perks I could get at my level.
