I think a better question is who does better without crafting, a pure warrior or a pure wizard. Very early on the warrior, then once the wizard gets some gear and a staff the wizard takes the lead, and then end game they're pretty close once the warrior gets spellbreaker and very strong end game one-hand swords. Double dremora lord even without any spell cost reduction gear is affordable and very powerful but the warrior is basically unkillable.
Endgame I would agree due to Loot you can pick up...but on a flat rate, you're not going to just STAND There (As a player) and take hits..you're going to Kite/Run/Juke and Jive, versus a Warrior who:
A) Even when blocks HAS to take damage and is doing ZERO damage due to being that close and having to block due to opponent hitting him.
Dual Wielding is VERY effective at lower levels due to that combo/spin attack...usually one of those + one more strike = dead anything at low levels. Higher Levels I do not know..I think that leaves you open, and as a PLAYER...you wouldn't stand there and let him do that to you.
I.E. If your opponent is dual wield (Forsworn are notorious for this and are tough to fight as a melee warrior) as a Mage, you're going to cast, cast...cast...and keep casting, Move...cast...taking no damage, and waiting for Regen to commence/slowly. Versus a Warrior who if he stops swinging, he is stuck. Has to deal with Ranged, so he has to close the gap WHILE taking damage (Dodging Arrow users on all my characters is tough, even my Rogue/Dark Brotherhood Master...@_@). Then you have to deal with Magica Resistance...
If both not chugging POTS, Mage comes out the winner. Warrior would have to chug pots or face death due to health regen is almost non-existant in combat, and sometimes out of combat is still slow so the next fight = one hit dead. (And Dragons do come out of no where!)
Personally, I still say mages are better...because as a warrior...you have to chug HEALTH and STAM Pots, versus a good mage who only has to chug Magicka Pots.
Mages though...Run around...Jump, Range...Kite...Mohammed Ali Process, FLOAT LIKE A BUTTER FLY! STING LIKE A BEE!
