Im not sure how you wish to implement party jump, since every character jumps to different distance, alterned by strength ... maybe by restrict it to shorter distance in group? Dunno ...
But i have to admit that personaly i also expected that it will work the same as it was in nautiloid, where "us" was following you without needing any futher instructions.
I still dont understand why cant we change Race for our hirelings.

Lets us play Githyanki as racist as they trully are!
