Was thinking about this the other day; I am assuming when they were designing GNB for this expansion, they wanted to keep as much of Draw and Junction as possible as it was such a key component to the jobs skill ceiling and enjoyment. Now, we don't know if they took into consideration how often a GNB would NOT be fighting against not standard(if we assume the standard is at least one of Tank, Healer, DPS) compositions, but I assume because they wanted to preserve some piece of original Draw and Junction(that of targeting an enemy for a desired effect), they most likely did not see it as larger issue. Unfortunately, even with the reduced role responsibility compared to Feast, there still isn't enough tanks(specifically) or healers in queue to guarantee that you will get put against a standard composition so GNB can utilize it's kit to it's entirety. I am also assuming we won't see a fundamental change to Draw and Junction till a major patch as it will require them to not just tweak current Draw and Junction, but code in an entire new ability.

It seems they still want GNB to be the "DPS Tank", providing large amounts of damage instead of consistent crowd control like WAR, or a major utility like PLD's Cover, to which I am personally fine with it as you can see equivalents of this in other roles when you look at jobs like SGE and DRG. The extra damage is of course always nice to have, and just the extra 10% can make certain combo's really put the hurt into the enemy team. The extra healing is nice as well, boosting the shields you get in Tank Junction, the heals from Healer Junction, and of course buffing Recuperate from 15k to 18k helping with GNB general survivability. This will also make Healer Junction stronger in those situations where you use it, which of course is nice to have. The mitigation on LB is ok at best. I would have personally rather had anti-cc as it is usually cc that will mess up a good GNB LB, but again I can't say no to free mitigation on a fast charging LB that can be devastating in the right circumstances.

Personally, I think if they could just change Draw and Junction now the job wouldn't need anything else. Going back and repeating that if they could make Draw and Junction akin to the Black/White Shift on RDM, where you had a 1sec ability that allowed you to swap between Tank, Healer, and DPS on a loop, that would be perfect. They could just add the Powder Barrel charge attached to current Draw and Junction to Junctioned Cast, so it's not completely lost. In my opinion GNB does more than enough damage, and it's survivability is good enough that it covers the lack of cc or utility the other jobs have, they just need to address the Draw and Junction jank.
