Yes, but is that a failing among warriors, or a gratuitous level of ability among the spellcasters? There's no consensus on the issue, as there are strong arguments both ways - hence, there's some credit for the argument that spellcasters need to have their options dialed back, rather than have the warriors' options increased.
Lets assume we have an RPG X, where the fighter lives up to its name, and is, well, best at *fighting* - best armored, best at handling weapons, best at tactics. Also assume that narrative control over non-combat situations are equal among classes. What weakness *should* the Fighter have in this fictive system to balance this?
