Or just don't take pack instincts as a power. I think it is great if you are playing a werewolf game, but if you are a single werewolf in a mixed group, I as a GM would not force you to take it.
On the other hand, you could talk to your GM and maybe let him give you a small pack of NPC wolves along with your pack instincts. Not like characters to play with, you wouldn't get additional actions. It could work by letting you do 1 wolf related declaration per exchange, so you could have your opponent "flanked" or something like that, that you can tag on appropriate rolls.
