Put a leash range on Flightmasters?

I would like to start by mentioning that I searched for both "Flight Master" and "Flightmaster" with the Forum's search tool and came up blank so I do not know if this is something that has already been reported or not but here goes.

It would be nice if some sort of leashing range was put on for Flightmasters. I have yet to see it in action; but for the past few days the Flight Masters in both Redridge and Duskwood on the Lordaeron server have been missing from their intended spots and how this happens (According to what I have seen 3 different people explain) is that Horde players somehow manages and goes out of their way to like pull / control them so far away from their intended spot that they just gets stuck in the middle of nowhere. It's good that the Horde shows that they can find things to pass time with given how good they are at the game, I'm glad to see that this has not changed since my last visit about 3 years ago to the server - But it is a tad annoying and allowing the flightmaster's to evade-run back, have a tighter leash-range or perhaps outright immunity would be appreciated.
