I did spend a lot of time getting that mount. Note that mount was only revered with Anglers, and I ground out Nat Pagle to exalted for the fishing hat (which I regrettably deleted, I suppose I can buy another…).
I did get a ton of use out of that mount, both in Legion and in BFA, and overall I was glad I did that grind.
But aesthetically I agree, mounts right now are super boring. We have these massive collections of mounts we seldom use because they lack functionality of the limited set of mounts that do more than move fast. Examples here are SKy Golem which lets you herb while mounted; the various 2 person mounts that let you bring along a buddy; the various underwater high speed mounts; the water strider that lets you walk on water; and the yaks that have vendors. What I find is I typically wind up using those mounts and every last character looks the same, and I take a functionality hit if I go for the style of using something different.
So for me I welcome this new mount system as I can now have a cool looking mount that fits each toon, and gear it out to do whatever I want. The Sky Golem will likely still be a mainstay, since herbing is so profitable, and it makes so much sense to do it on the Sky Golem. But it will get even better if you can add water walking to the Sky Golem…now you can herb and walk on water…good stuff.
