I'm enjoying it so far.

The fact that insta-60 characters would be locked out of class stories was made abundantly clear and discussed extensively both here and elsewhere. Of all the things to complain about, this seems like a particularly odd choice.

Was AC changed? I thought I saw in the patch notes that it wasn't...

IMO, it should never have been possible to do world bosses solo.

Based on what, precisely?

I agree with the OP. I'm specifically looking forward to grouping up to take down world bosses again as well as random heroics. Also, I find the grind from level 50-60 to be fairly tedious after having done the standard progression of quests a few times. I can now hopefully find some alternative routes to get these to level 60 that I have perhaps not done as many times.

Isn't access to materials and schematics really the biggest hurdle to making money with crafting? I don't see how buying a new character with maxed skills is going to change that much. It's not like leveling crew skills is really all that difficult or even all that time-consuming. It's getting the schematics you want that's somewhat of a pain.

I'm looking forward to seeing random Heroic Mission groups forming on fleet now. Should be fun!

Your deeply silly redefinition of content removal aside, my point is that a whole bunch of people got really bent out of shape over what turned out to be not a big deal whatsoever. Some of those same people (not naming any names!) are once again bent out of shape, and I think the end result will be quite similar. Time will tell.

Remember when 3.0 was about to come out and how lots of people were REALLY MAD about how our dps was getting nerfed, and then a few weeks after 3.0 came out nobody cared anymore? I think this will probably be kind of like that.

I'm pretty pleased with pretty much all of the new stuff they announced, including level-syncing.

Doesn't bother me a bit. In fact it might revitalize some old content, like world bosses.

I've decided to take this annoyance and use it as an excuse to finally ditch bitraider for good. I should have done it long ago, but I didn't want to go through the hassle of downloading the whole game again. This is the last straw, though. I'm ridding myself of bitraider once and for all. I encourage others to do the same!

Nope.

To answer your question without getting into spoilers, yes there is very much a threat that we didn't take care of. How this will relate to the events of KotFE is not currently clear to me. I suppose we will have to wait to find out. Of course, there are...ways...of finding out additional information, but their discussion is discouraged in the official forums.
