In FFXI, when ZNM's were introduced, that system was my ABSOLUTE favorite. Yes, earning points to buy pops was a chore of a process at times, but the actual system itself was perfect. The rewards were pretty impressive, and you had a 100% shot at claim of your NM because you spawned it.

Other note I wanted to make was, being new to XIV, when I did my first leve and noticed the enemies spawn from my leve JUST for me, and I didn't have to fight for claim was really impressive. I don't play many MMO's so with that said this was new to me and I really like this system.

Instanced does not have to be something that loads you into a different zone. I can see the feeling of disconnect from that. But rather it can be in the open world with exclusive claim to you and your group. I have no problem with this whatsoever.
