I'm building a fighter Tank. this is a question of what you can achieve with quickdraw, two weapon fighting, fighting with two shields & free actions.
Quickdraw Shield (Light Wooden or Steel)
"...If you have the Quick Draw feat, you may don or put away a quickdraw shield as a free action."
From the FAQ
"Two-Handed Weapons: What kind of action is it to remove your hand from a two-handed weapon or re-grab it with both hands?
Both are free actions...."
"...As with any free action, the GM may decide a reasonable limit to how many times per round you can release and re-grasp the weapon (one release and re-grasp per round is fair)."
point 1: could I feasibly declare that I am two weapon fighting, taking those penalties, and use a one handed weapon (heavy shield) with two hands to get my strength x 1.5, use a free action to let go with one hand, use another free action to draw the shield and then use a shield bash?
point 2 if part 1 works then this bit is more GM discretion, could I then perform a free action to stow the quickdraw shield and make the same action all over again for a higher Base Attack Bonus (fullround attack)
