It's been this way for almost 10 years. Why is it suddenly a big issue this tier?

Because there’s a PF healer drought. Whether it be increased healing and mitigation demands or people are tired of healing or what not PFs are not getting filled out and always missing healers.
This was brought Up in Q&A of the 14 hour stream and
YoshiP responds “then play healer yourselves.”
Players “with what gear, we’re already half way invested into our main roles. We can’t afford to swap to another role mid tier.”

TLDR
PF needs healers. YoshiP tells players to go heal. Players are willing to heal but can not justify getting healing gear mid tier because of the gear and time gate system.
