I'll believe it when I officially see it in writing.
If true, I believe that stating NRs can't party hunt at all is better than stating that they can party hunt, but that they are required to fill only their own tag(s). Too many times during party hunts, the same guy gets all of the mature bucks in front of him, and only him. It would be a liability to me and the rest of my party to have restrictions placed on who in the party can shoot what sex deer and number of deer, based off of their personal tags in possession. That's what makes it party hunting. The ability to pool and fill tags as a collective group.
A dude that only has a doe tag, that only he can fill, won't be hunting in my party, because the chance a nice buck walks 20 yards in front of him is extremely high, and he won't be able to shoot it. It would be like having a teammate standing under the basket that's only allowed to shoot three pointers. You're better off not even having him on the floor. He's more of a liability than a benefit.
Screw with the ability to pool / fill party tags and there's no incentive to group hunt.
I'm personally a strong supporter of the party hunting practice. It's been around much longer than solo hunting practices.
