We should get more job mounts, but they shouldn't be obtained the same way as the tank mounts, I don't think you get how harmful it would be for DF, most of those tanks in DF aren't tank mains, incentivizing them to stay on their healer/dps mains or they lose a mount would have a big negative impact on DF queues.

I understand that the tank mounts exist to entice players to play tank, but let's be real here. Most people obtain their tank mounts within quarantined spam runs of 1-2 minute content rather than the original intended method.
You don't know that, the fact that they did a second round of tank mount achievements tells me they actually do work to get people to casually tank, maybe not everyone, but it doesn't need to reach that far for it to be effective.
