Okay. What about allowing it multiple times per round, which means you can have one partner TWFing, triggering abunch of attacks from the other partner with a greatsword.
Yeah, Synchronized Strike and Defense need new names. What it really is is partner A attacking an opponent, Partner B, who is familiar enough to recognize when and how A is going to attack, is ready to take advantage of that opponent's distraction. With Defense, A gets attacked, B knows how A defends well enough to know how to take advantage of that distraction.
Maybe something like Twinned Strike and Retaliatory Defense.
Alright, if were not doing AoO-passing, we'll need another powerful class feature.
I may use the name "Synchronized Strike" For some thing where the two partners attack simultaneously, if both hit the enemy makes a fort save DC 10+ Damage Taken or else get's stunned.
Hmm, some other potential ideas
Two-Man Takedown: One partner makes a Trip check against an opponent, if this succeeds, the other partner may (provided they haven't gone yet), make a single attack at their highest base attack bonus on the now-prone foe. This attack automatically threatens a critical.
Edit: Also, maybe somthing that lets the partners occupy the same 5-ft square (Great for narrow tunnel fighting).
