I don't want to sound rude here, but ...
That is not what I said at all, ergo you *are* arguing against a strawman.
Build a 3rd-level Human Fighter, Core Rulebook only, using the available wealth guidelines. Look only at your own character sheet.
I, the DM, tell you that I'm going to place you into a room with an orc (presumably guarding a pie). Without knowing anything else about that orc (because of your claim that you can tell with a high degree of accuracy your combat capability in 3E by only referencing your own character sheet), what are your chances of defeating him in a fight?
You can give me a +/-10% range, if you want.
Your example is a strawman. It would be equivalent to asking you if a 4e character could pick a lock, without telling you what kind of lock it is.
Can Aragorn defeat an orc? How reliably? All we need to know it is that is a fairly run-of-the-mill orc, and we should be confident he can defeat it.
