Gameplay: Private Instancing?

[Hyncharas]

I know it may sound absurd to a lot of people, but it seems to me that if the Devs want to pursue eSports with the MLG or other competitive ladders with the Battle Islands and parts of a continent, you can't do that if there's always going to be some random, public players dropping in and interfering.

To avoid griefing from teamkilling in such situations, might we see the introduction of private instances that create a no-zone for everyone not in assigned teams?
