It's unlikely. Thought the changes to encounter design were not going to be fully implemented until 7.2?
Regardless, the core issue remains clear.
To be a support, is to accept that the game is not going to be fun long-term, or your enjoyment is highly dependent on external factors.
You made the mistake of playing the jobs that are not fun inherently. And until that fundamental issue is tackled, everything else is just bandaids, lip service, or outright lies. As we get more and more gear, we'll slide right back into where we were before.
And for those non-savage, non-EX folk, they still should have a fun job to play. Not that it's much better on the EX end to be honest, I had to wait 30 mins or even longer for healers to fill my EX learning groups this last weekend. And when I drop down to dungeons, I've had longer than usual queue times on tanks (only have GNB to level now), and probably some of the worst healers I've ever seen in this game since I started in HW. Good thing I'm playing tank and can drag them through, or if not, I can just leave for the next tank to get frustrated at the sound of Cure I spam while I do literally anything else.
