OK, thanks guys. Looks like the consensus is B.
Hmm. I was trying to find a way to make a sort of keep-away fighter.
I attack foe from reach on my turn, marking it. Foe steps in to close with me on its turn. I use polearm gamble to get opportunity attack for that movement (at bonuses to attack from other feats). I use Heavy Blade Opportunity to make that opportunity attack a Footwork Lure attack. I slide 1, foe slides into the square I left plus another square with Staggering Weapon. Foe is now once again not next to me (but not so far away they can charge).
But it sounds like the consensus is that will not work with a Staggering Weapon.
OK, so option 2 is instead to use the Fluttering Leaf Style feat.
Fluttering Leaf Style (from Dragon Mag. 368, Pg. 61) lets you shift 2 squares instead of 1 with Footwork Lure, but you must end the shift adjacent to the target.
So similar scenario. I Attack foe from reach on my turn, marking it. Foe steps in to close with me on its turn. I Use polearm gamble to get opportunity attack for their movement (at bonuses to attack from other feats). I use Heavy Blade Opportunity to make that opportunity attack a Footwork Lure attack. I shift 2, to the other side of the foe, foe slides into the square I left. Foe is now once again two squares away from me (but not so far away they can charge).
Anyone see any reason why that does not work?
