EasyMount

A simple macro to summon your preferred mounts.
If you are allowed to fly in the zone it will summon a flying mount, otherwise a ground mount.
In Dalaran it will summon Ground mount, except in Krasus Landing.

Usage:
Create a macro, name and icon of your choice.

Use this as the Macro text:
/run EasyMount("groundmount", "flyingmount")

Replace "groundmount" and "flyingmount" with the names of the mount you want to summon. You can put more than one, separated by a comma, in that case it will summon a random mount.

Example:

/run EasyMount("Armored Brown Bear, Black War Bear", "Time-Lost Proto-Drake, Bronze Drake, Turbo-Charged Flying Machine")
