I should have taken them serious when they said they had a "cool mount".

Anyone who still plays Vanguard has a nice bit of reward waiting for them - the loyalty gifts are reworked today. They now grant a choice between two pieces of in-game gear, the Adherent custom title added to your name, and (prepare to groan) the K.O.O.L.E Mount, with reassurance that yes, it IS that cool.
