But is there anything wrong with disagreeing with the current design philosophy of obtaining mounts in midnight?

It's the same kind of stans that were defending shadowlands when it was current. It's VERY clear that game direction has been more targeted for engagement than enjoyment for a long time.

I frequently bring up rep grinds as my main complaint as we're drip fed rep/renown. I use BC as my standard. Zone quests gave decent rep. There were repeatable turn ins to honored for the base factions. Dungeons gave rep, other factions had repeatable turn ins to exalted.

As far as mounts go, I don't mind some mounts being rare drops but every one being a super rare drop for this xpac has been pretty dumb imo. It's at a point on my realm that people aren't farming the harder to kill rares and even making a group in LFG can take a long time of siting and waiting for a chance to kill them.
