I'm going to throw my opinion into the pile since they did say they wanted feedback on a lot of stuff going forward at fanfest. I am assuming based on their opening argument against Blue Mage that no limited job will ever be allowed in current content. Maybe BLU can do WhateverNewRaid Turns 5-8(S) in 5.4 or 5.5, but I don't see them being allowed into 9-12(S) until after the expansion. That goes for trials as well. I could be wrong, but all we have is conjecture and their statements do not instill any faith in me that it will be different. And no, I wasn't talking about Blue Mage when I wrote the segment below.

tl;dr: I do not like limited jobs and hope they don't continue with them.

In the best case scenario: I totally love the job, best thing ever, 1001/10, game of the year, whathaveyou. Instead of getting to play it though, I'm screwed on raid nights, any time my friends want to do roulettes or alliance raids, or I want to do current raids and trials. Heck, my friends could want to do FATEs or Hunts or whatever and I STILL can't join them on my potential favorite job because the level cap is arbitrarily low on that patch. Its possible I can't do Deep Dungeons at all, or am forced to always go solo, and I highly doubt they'll let a limited job participate in whatever Lords of Eurekadem is in 5.0+ since they don't seem to want you doing current content when you could go in essentially naked and useless since you didn't do the job's gimmick and lack spells/equipment/whatever. So I have this job that I would potentially love to play, but couldn't play in massive swaths of content, even with my friends in premade parties. I can't even use the job to get relevant tomestones for the jobs I can play in that other content until some unknown point in the future. It could be X.1, it could be X.56. Nobody knows.

I'm not interested in constantly thinking to myself, "man, I could be having so much more fun right now." Nor am I interested in feeling like I'm being punished for liking a job and raiding, or doing roulettes or whatever. I don't want to chose between having to force myself to play less fun jobs for all the current content I like, or be shuffled off to solo content to play a job I like because the devs made my hypothetical favorite a gimmick.

It completely kills my interest in any job they might throw into the limited category.

I'd rather they just use that effort to make the existing jobs better or more engaging. Just my 2 gil on limited jobs going forward.
