Being a tank or a healer require a certain stat of mind not everyone have.
Clearly, not everyone is fit for thoses jobs, either beacause of pressure, anxiety or other reasons. Besides, often dealing big damages has always been more attractive than being the team's punching ball!


Adding new tanks won't change queues in a long term, and as I remember from Heavensward, sure at first there was a lot of DK... but most of them having no clue how to tank, so no queue, but no clear either. Most of them disappeared when they reached lvl 50.

As for myself, I'm fine with it, when everyone will be rushing lvl 50 and 60 with those new classes, I'll be fine being a tank and enjoying instant tag haha! Part of the fun of being an unattractive job
(PS: love the idea of asking some gils for insta queue with me... 50 000 Gils seams fine for me )
