As we had in ShB, where trial mounts were these little baby dragons that were horribly undersized for anyone besides lalafels, we seem to be repeating that trend with Endwalker. The new lynx mounts from the 2 extreme trials are woefully small in scale compared to our characters to the point of looking extremely goofy. Along with having disproportionately small heads.
I've been of the opinion that the art direction for mounts in this game is very poor as almost everything is some sort of goofy creature, especially when we have month long beast tribe grinds for something like a tiny little flying piglet. Or it will be something cool, but it's a mount that looks absolutely ridiculous flying (like the Ananta Elephant). Seriously when we've had flying for several years now it's silly that we keep getting ground mounts that can just magically fly without wings or anything.
But as far back as Heavensward we had the lanners which were very large and very cool looking, along with obviously making sense as flying mounts, but it since then the mount design has only gotten worse. The Gwibers and winged lynxes would be perfectly fine though, if they weren't so absurdly small. I'm not sure if this is just them continuing their trend of making mounts look goofy (for whatever reason), but I don't really care to grind for some mount that looks stupid. Please scale up mounts to properly be sized for our characters. I'm not saying change the gwibers or the lynxes now since I'm sure people who already have them like them as they are, but going forward, can we please at the bare minimum have mounts properly scaled up for our characters. And please stop making ground mounts. Every single new mount that's not from an extreme or savage is some sort of ground creature. We've had flying for several years now, the mount design should be reflecting that. It makes zero sense to keep making dogs and pig mounts that have no logical ability to fly and just slapping flight on them, it looks beyond stupid.
At this point though, zero of the new mounts, save for the new savage mount (which I won't be getting this expansion because I don't do savages), interest me at all for these reasons and I'm sure I'm not the only one who isn't bothering to grind for them.
