why is this forced on us and not an option?

I dont see hotbar 1 as my primary/main hotbar, I only had it in the position it was in because it has the hotbar lock on it. I was using hotbar 1 for my companion chocobo you know to summon, change stances, make him follow you or release him. that left 5 slots which I put mounts into, I have since changed which bar I'm using for that.

OK but it's important to understand that the way the game is organized, they're going to be futzing with that hotbar a lot. They're definitely not going to be disabling the current change when it comes to things like battlements, which something tells me will have a measure of importance when they add airships and flying mounts to the game.
So while your field mount such as the magitek armor or the goobbue will probably get a passing fix, it's important to note that your specific playstyle runs counter to what the developers take into account when they make changes to the game. You will continue to have issues such as this so long as you use Hotbar 1 for non-primary features.
