TWO-WEAPON FIGHTING [GENERAL]
You can fight with a weapon in each hand. You can make one extra attack each round with the second weapon.
Prerequisite: Dex 15.
Benefit: Your penalties on attack rolls for fighting with two weapons are reduced. The penalty for your primary hand lessens by 2 and the one for your off hand lessens by 6.
Normal: If you wield a second weapon in your off hand, you can get one extra attack per round with that weapon. When fighting in this way you suffer a –6 penalty with your regular attack or attacks with your primary hand and a –10 penalty to the attack with your off hand. If your off-hand weapon is light the penalties are reduced by 2 each. (An unarmed strike is always considered light.)
There are two schools of though here. One that says anytime you want to count as "wielding" a weapon for AoOs, you must take the penalty, one that says you only take the penalty on the AoOs. It hinges on your interpretation of the bolded text above. Your example is pretty much the poster child of why so many people rule that you must take the penalties all the time. I also think that a changing to one ruling on the way weapon wielding is handled is a lot more reasonable than banning reach weapons entirely.
Other than that discussion, I am failing to see how you can threaten over a 50' area, even with Enlarge. I am also wondering how you have enough castings of Enlarge to last all day, how every character would have the Combat Reflexes feat (a must have if you're relying on AoOs), and why your opponents couldn't cast on the defensive, or move out of your range to pelt you with ranged weapons. Some more details about these tactics would be nice.
