Sure if SE did the same thing Wildstar did it wouldn't HURT the RP community, but then again could it ever be better than WS?
If SE could figure out how to get this system to work better and encourage more communication everyone in the Wildstar community would be jealous how awesome FFXIV was.
The ward system is a great idea that hasn't been fully implemented properly, hence why it's not that great. Given the choice between Instances and a "Fully functioning ward system" a majority of RPs would pick the ward system.
