Whether it is possible to make instant movement instead of flight by a taxi as an option. Well when a lot of people play on the server. And when to the people plays 10 people, instant movement very much would even be useful.

Perhaps it is already realized, but I haven't found such option in a config.

I apologize for my bad English

you mean teleport??
so when you are at the windrider in stormwind and need to go to westfall, then you dont fly but get teleported?

I mean when you sit down at the bird, you fly the whole route in real time.
And with the option enabled, once you have appeared in the final destination of the flight.

Оption "InstantFlightPaths = 0" in trinity core.

Added to the core. Thanks for your question.
