You can take the full attack action, make an attack, and then decide to trade the remaining attacks for a move action.
Can you take the full attack action, make an attack, then quick-draw a shortsword with the off-hand and make an attack?
If not, why not? Show me the rule.
Your model contradicts the D&D general rule that one can attack, judge the effect, and then take a second attack if available. I'm trying to figure out what rule you've found that states that contradiction.
You said, "I'd allow him to draw a second weapon, as long as he doesn't wield two at the same time if he's already made an attack without taking TWF penalties."
So, to be clear, you'd allow someone who takes the full attack action to attack with the longsword (currently only wielding one weapon), drop the longsword as a free action (currently wielding no weapons), quick-draw the shortsword with the off-hand (currently wielding one weapon), and attack with the shortsword? And, since at no time is he "wield[ing] two [weapons] at the same time," he doesn't take TWF penalties. Right?
If this isn't what you said, how is it not permitted by what you've said?
Another question: How about the guy wielding the two-bladed sword? In your model, he can't attack once, then decide to take an off-hand attack, right?
So, to sum up:
In your model, the general rule that one can attack, judge the effect of the attack, and choose to attack again doesn't fully apply to two-weapon fighter, because ...
In your model, the general rule that one can attack with a weapon, then quick-draw a second weapon and attack with it doesn't apply to two-weapon fighters.
So to make your model work (sorta, I guess), you have to change two general rules of D&D combat. Right?
Whereas the alternative, my model, and Customer Service's model, says that as long as you accept the penalties for TWF on all attacks, you're eligible to take an extra attack with your off-hand.
