Yes, I know!
As some of you aware I have written something similar before reference our mounts. My previous post Is there a reason!.
My new thoughts/opinions also have to do with mounts, but this time their ability to swim/water walk. We have something like Vashj’ir Seahorse that is limited to the zone… WHY? because you have created another one that is not limited Subdued Seahorse Why aren’t we allowed to use the one we already have? Fine, I’ll let it go…
Let’s talk about Vicious War Riverbeast! I understand that this mount is Alliance only and that it is a PvP mount but as far as I know hippos can swim… Why can’t our mounts? You have an Azure Water Strider that walks on water, and striders do actually walk on water… why do you separate certain mounts from their ability?
All of our mounts should do as they would if we could summon them in real life…between hundreds of them, could you imagine how much more immersive it would be to collect them? To summon that particular mount with the ability that you need at that moment. Stop making all mounts the same, because they are not!
A little story for you all 
So I am running around on my Sky Golem and collecting herbs in BFA- because BFA is boring or (I am one of those folks that say that there is nothing to do in BFA). So I come to a spot where you need to climb a mountain but I can’t seem to get to the spot. 1. flying will make this easier but we can’t fly yet…2. I could continue to walk around and try to find a way to get to that spot…3. I’ll just use the boost ability (let us say 3-5 seconds burst) on my Sky Golem to propel myself and then glide down, like all the flying mounts supposed to do. (See what I have done there? )
Some of us do not care for raiding or M+ runs but we still love the game and want it to be more immersive.
What do you all think?
