The problem is Pawsplay, a 1st level warrior is still weaker than a 1st level PC class.
That's not actually a problem for what I said. If you added the 1st level warrior's abilities to a 1st level wizard, you would discern the fighter's advantage over the warrior. By the same token, you can subtract the warrior's abilities from the wizard to see how much a PC has over a non-PC.
The conclusion is that compared to Joe Off the Farm, a PC has a better ability score array and one extra feat, by dint of being heroic.
If Joe Off the Farm can spend a few months becoming a 1st level warrior, why can't Magnificus the Wizard? Moreoever, why doesn't the wizard, who has regular access to one of the best sparring partners around, surpass him? As long as Magnificus doesn't acquire an extra fighter feat and reshuffle his ability scores, we haven't broken any of the assumptions made due to the PC/NPC split.
In short it doesn't really make much sense that by level 10, a wizard's weapon proficiencies are still garbage. It actually makes less sense if the wizard has a single martial or exotic weapon proficiency, and despite using this skill from time to time, does not develop the same breadth as a fighter as Joe Off the Farm.
