So, Blizzard wants these monthly events to keep people busy for the entire content drought until Legion, and beyond.
Two mounts, both reused old assets, each taking roughly 5 months with event quest and a reasonable ~15 runs for each available week. Can't play during one event? Tough luck, it's gonna take you even longer.
How is this enough to keep the average player interested? With such a long wait, the rewards become meaningless. When they could have been exciting if you could just sub and get one of them now, they are just off-putting. Even I, an avid mount collector who stubbornly pushes through grinds, think this is way, way,
way too much.
It's so unreasonable that people are just not going to care. "Screw it, if it's gonna take that long it might as well take longer. I'll get it anyway while I sub for better content." Or, "I was willing to give the game a chance for this dangling carrot, but
I know I won't stay subbed for 5 more months, so I'm not getting it anyway. Pass on WoW." This is what the average players will say.
So, if you came up with this system, and you want it to be long-lived, why not dig deeper into the sack? Let people earn enough tokens each month for roughly one mount, and simply add a lot more of them! People will not farm 5 months for a single mount, but they might farm 5 months for 5! That sounds more fair, doesn't it?
There are a lot of unused or not implemented mount models already in the game files, and let's face it, those models, even the absolute best of them, are showing their age. When are you going to end up using them? And there is very little cost of adding them, all the models already exist!

And whow, that's a lot of mounts! All Blizzard has to do is implement them and add them to the vendors, and then, even if players aren't interested in farming them all, it's certain there will be something here for
everybody's liking. Even if they're all reskins, and more than half are ancient.
