Seems like a touched a raw nerve, there.
Let's see here....you need wisdom (common sense, perception, self-discipline, empathy) to gain effective combat superiority.
We can take a classic example from recent literature, and see if we can fit him in: Sandor Clegane from ASOIAF. Were I to draft up his stats, he'd have a wisdom of LESS THEN 10; probably in the 6-7 range. He is violent, rash, near-sociopathic in his lack of empathy, a drunk, and horrifically ill-tempered. These things are what makes him a hellish fighter - he is a terrifying weapon of destruction but would be either be nerfed to hell and back because of his horrid wisdom stat OR you'd have to ignore his stat in roleplaying to grant him his battlefield capabilities.
I'd build him as a Slayer with high strength and dexterity, but that's neither here nor there
.
That being said, you don't need a high wisdom to be a good fighter. There are good Str/Con, Str/Dex, etc. builds. The wisdom-based bonus is just the option presented in the PHB; if you want support for other archetypes, there's other options out there. This is nothing new.
If anything, I'd tie the combat superiority to dexterity (hand-eye coordination, agility, reflexes, balance) not wisdom. I can't really think of any wise fighters in literature or history...maybe wise commanders (as in a warlord class)...
Eh. Interpretation of what each mental stat represents has always been a sticky issue. What we call 'wise' has very little in common with some of the aspects of D&D's Wisdom score. Wisdom represents such things as perceptiveness, intuition and willpower, as well as more classical definitions of 'wise' such as patience and insight.
Besides which, dex-based fighter archetypes have Combat Agility to fall back on, which replaces Combat Superiority with a dex-based approach; alternatively, take the Agile Superiority feat, and you can use Dex for Combat Superiority.
Seriously, the fighter is the most well supported class in 4E, with literally hundreds of feats and powers. I would say that while they can't represent every warrior archetype out there 100%, I think they're close enough.
Also, for the roleplaying aspect, I feel that 4e has taken the stats way out there. So many classes rely on multiple high (12+) stats to gain access to basic attributes of the class that beginning characters are more and more like body-building philosophy-spouting quantum mechanics-solving circus acrobats, stat-wise. It's just an awkward mechanic sometimes.
You're going to have to give examples here, because this is literally the first time I've heard anybody say this. You need certain scores to get access to certain feats (and thus builds), but that's nothing new. What class requires you to have high scores in multiple stats to be effective, exactly?
As a sidenote, note that the suggested stat generation method is point-buy, which starts with no points spent at 5 10's and an 8. Getting a 13 in one of your secondary stats is really not much of a pain at all. To give an example, my elf cleric|invoker at level 1 had Str 8, Dex 13, Con 16, Int 13, Wis 18, Cha 10. Having both 13 Int and Dex do literally nothing for me rules-wise, but I felt it fit the character a lot better that way; most importantly, he's a scholar-type, and I wouldn't accept anything less than 13 Int
.
EDIT: Ninja'ed. And I'd stat big brother Gregor as a Battlerager, but Sandor definitely looks Slayer, to me
. Also, sorry for dragging this thread off-topic.
