The changes to Trick Attack impacts every class, and not in a good way.

I'll be a bit cynical here... So which of those classes (bar healers since at that point we'll probably take anything if it means we have something to do other than the barebone DPS rotation) is willing to take a dip in their aDPS to boost others? Genuinely asking here because most often I see Ninja Changes viewed by this prism and not the class itself (other than having more stiff Ninki management once that becomes a thing)

At the end of the day you're talking about numbers that you'll only see with a third party website and tool. Like that's great if it ultimately got a buff in 6.1 but who really cares, NIN was performing just fine in savage content beforehand so it didn't really need it. I play NIN pretty casually but I enjoyed playing the one class who could throw up a one minute buff for other classes to take advantage of, and of course while playing other classes being able to dump resources into that buff when it was up. That's something much more tangible during gameplay than colored numbers that I'll never bother looking at anyways.
