So it's taken me quite a while to save up enough to buy a horse. Is it worth it? All input is appreciated. Thanks guys.
Definitely.
Especially for the Alliance War if you'd ever like to be a part of it,
as well as the extended storage space.
Additionally when you reach higher levels, even if you do not use any guild traders to sell anything you find (i.e. you just vendor it all) it doesn't take you too long to earn a decent amount of coin to cover the mount cost.
