As we all know, Mineplex 100% respects Mojangs EULA *cough*Immortal rank*cough*. However, some of the mount skins available in the clans shop (Cow, sheep, rainbow sheep, cake, and melon) violate the EULA. While the mount skins are cosmetic, their hitboxes aren't. Due to mounts being so overpowered in the tank meta, being able to stay on your mount to pvp is a huge advantage. Being hit can cause you to be kicked off of you mount, so being able to avoid getting hit is therefore an advantage. The smaller hitboxes given by certain mounts allow for players to avoid getting hit, and while it's a small advantage, it's an advantage. A simple fix would be to just change the hitboxes of the smaller mounts to that of a horse.
