Reps probably wont respond to this to keep the ambiguity of the patch intact for now. The Devs/Reps said it would be before end of summer but also did not say it wouldn't be in 1.18. Still a 50/50 shot at they pulling a good surprise move.

I also see Dungeons being ultimately easier on Classes than Jobs. At the moment Classes are the jack of all trades which has made ALL content up to this point a complete cake walk. So you can have 8 classes who have heals and damage mitigation abilities in an 8 man dungeon as opposed to you having 2-3 healers 1-2 tanks and the rest DPS when we can switch over to jobs.

If SE was smart they would indeed add jobs in 1.18, get the balancing out of the way and start focusing on more content as the top priority.
