Halfling cavalier favored class bonus, huh?

Quote:

Add +1/2 to the cavalier's effective class level for the purposes of determining the damage he deals when making an attack of opportunity against a challenged foe.

What is this good for? So, a halfling cavalier can deal more damage to a challenged foe who provokes. That's...nice, I guess. What would go well with that? Paired Opportunists and a friend with Greater Trip or Greater Drag maybe?

It'd be good for challenging the spellcasters and archers... assuming you can get and stay in melee with them.

Broken Wing Gambit (Combat, Teamwork):

You feign weakness, making yourself a tempting and distracting target.

Prerequisite: Bluff 5 ranks.

Benefit: Whenever you make a melee attack and hit your opponent, you can use a free action to grant that opponent a +2 bonus on attack and damage rolls against you until the end of your next turn or until your opponent attacks you, whichever happens first. If that opponent attacks you with this bonus, it provokes attacks of opportunity from your allies who have this feat.

And

Paired Opportunists (Combat, Teamwork):

You know how to make an enemy pay for lax defenses.

Benefit: Whenever you are adjacent to an ally who also has this feat, you receive a +4 circumstance bonus on attacks of opportunity against creatures that you both threaten. Enemies that provoke attacks of opportunity from your ally also provoke attacks of opportunity from you so long as you threaten them (even if the situation or an ability would normally deny you the attack of opportunity). This does not allow you to take more than one attack of opportunity against a creature for a given action.

Hit them, now when enemies attack anyone in your melee line everyone gets an attack of opportunity, with +4 to hit, and you get that, and +1/2 level on top of challenge damage. They just died.
