Really bad idea, it's enough that WoW is now desperate enough to copy other MMOs but you don't have to make everything the same actually. If you like the GW2 systems then go play GW2, it's a crazy revolutionary idea i know but you can actually play...two MMOs!

FF14 has easy to access flight and that is good, same as the GW2 system is good.

So please stop with the "I play this MMO now so i have to change it into what i liked about this other MMO" attitude. Just play the other MMO then.
