Oh of couse an open Nomad ID would be more limiting than the Keeper ID. Ala the SCRA.
The real issue is simple - the admins don't seem to want it to be open. Another issue - which may be part of the admins reasoning is this:
Take a look at this thread - look at who wants the nomad faction to be opened up. Notice how they have little to no knowledge of nomad lore? Yea - that would be an issue if they decided to play a nomad. Nomad RP is some of the most difficult to grasp. Hence why they've always been closed and why they have a unique recruitment method.
Opening up the Nomads and then limiting their ZoI and such prevents them from role playing their faction properly. If the faction can't be role played properly by an indy - why have an indy?
I'll be straight with you - the entire reason I've not joined the K'Hara is because I can't stand the mindspeak stuff. It is annoying, but I understand it is core to their role play. I highly highly doubt anyone here barking for an open Nomad would bother with it on their indy nomad. They'd forgo years of role play and player written lore merely to have purple guns to pew pew with.
Again - it is entirely worth noting that John has requested the Nomad faction follow the lead of the SCRA. Admins are the hold up - so quit bashing the K'Hara. Go bash an admin.
