Yeah, it's sheer utter nonsense that the wizard is better than everybody else. The wizard does have a lot of power, but it's meant to be that way for the wizard is meant to be artillery. The wizard's greatest weakness is that they are not close combat people. Especially in 1e and 2e. In 3e they could multiclass far more easily and actually take a level or two in fighter, but that also means sacrificing some levels which could be used to increase his magic.
In fact. I'd bet that if you took three low or first level fighters against one mage without his spells, the fighters would win. The mage must be a minimum of tenth level. There must be no magic items either, for both sides. other than that, there is no limit to other equipment.
I'd bet that the fighters would win. Or do tons of damage.
Probably even without armor.
The point to this is to illustrate the great weakness of the mage. A Cleric also has this problem, but not to the extent mages do. Because Mages can't use armor. And fighters have tons of hit points. In 3.5e a tenth level Wizard is not likely to have more than 86 hit points, assuming a Constitution score of 18 (which gives a +4 bonus to hp per level) and mages are not likely to have that high of a Constitution score. This doesn't count the toughness feats though.
In contrast, a low level fighter, let's go ahead with first level, could start out with a maximum of 14 hit points, not counting feats. Three fighters have a potential damage of with a longsword of d8 damage of dishing 24 points of damage per round, with a probable average of 8 per round, without any Strength bonuses to damage. With a Strength of 18, that's a further potential of an additional 12 points per round.
A 1st level fighters' BAB is +1. A wizard's BAB is +0. A Strength of 18 gives a +4 to hit for a total of +5 to hit. A wizard is not likely to have this high of a strength.
Since a Wizard can not wear armor, they would have an AC of 10 without Dex or magic item bonuses. That means a first level fighter would need to roll a five or higher to hit a tenth level Wizard. How long can a wizard last against that?
Give the fighters chainmail, and that means they'd have a minimum AC of 15. With a shield that would increase to 17. If a wizard didn't have any bonuses, that means a wizard would have to roll a fifteen or seventeen or higher to hit. Plus a wizard's more than likely to have a a d4 dagger, or a d6 staff. Without any bonuses, that would be two or three rounds before defeating just one of them.
Do the math. The fighters would win.The fighter really overshadows the wizard.
Of course, single lightning bolt would take the fighters out. Maybe. Even if the Wizard did have his spells, he could still lose them because of these rules that many are overlooking:
Injury
If while trying to cast a spell you take damage, you must make a
Concentration check (DC 10 + points of damage taken + the level of the spell you’re casting). If you fail the check, you lose the spell without effect. The interrupting event strikes during spellcasting if it comes between when you start and when you complete a spell (for a spell with a casting time of 1 full round or more) or if it comes in response to your casting the spell (such as an
attack of opportunity provoked by the spell or a contingent attack, such as a readied action).
So, facing three first level fighters, that's a potential of three times of losing the spell. However, of course, a single lightning bolt would take them all out which is why you would need one of them to be an archer. And this is a
tenth level wizard we're talking about. Or the wizard could cast a magic missile which would be 5d4 + 5 points of damage, for a range of 10 to 25 points of damage. Still, that's against one opponent. And the magic missile can still be dispelled depending on initiative. A smart fighter would delay the attack until the caster started casting so they could dispel the spell.
Even if the Wizard would be given magic items to increase AC, the fighters still have that huge bonus of plus 5 to hit for every melee roll. That means if the Wizard had an equal AC they would still need to roll a 10 or a 12 on a d20.
Higher level fighters would of course have more attacks. A tenth level fighter has two attacks and a BAB of +10/5 which means +10 for the first attack and +5 for the second one.
And that's why they turn to magic.
Another way to test this out is that you can play DDO (Dungeons And Dragons Online) and play a Wizard or a Sorcerer and see how far you actually get on your own. It's free to play. or even other games such as Neverwinter Nights.
There you can see the strengths and the weaknesses of a mage.
I wonder if these anti-Vancian magic people have actually played a wizard or just read about the class and never played it.
I hope this little example dispels the nonsense of a wizard is so superior to the fighter that the fighters are absolutely useless.
If anything a fighter is superior to a wizard. But neither class can do everything, which is why they form teams so they can compliment each others abilities.
However, the example uses 3.5e rules.
And the big difference between literature and RPGs is that a writer has full control of the characters and situations they write about.
in short....
FIGHTERS KICK ASS! They are not a useless class to play.
