Hi welcome back

Leveling : dungeons are the best way now. Of course if you are a dps and not grouped with at least a tank or a heal you might be doing some fates, or leves while waiting duty finder.

Community : 90% don't care and didn't care about any hatred (yeah I made up the percentage but you have 2 millions accounts and I haven't seen a forum thread that counted 10K different users arguing, and even so that wouldn't be representative) Community the same, nice and neutral are majority and you have the few toxic that make a lot of noise.

Content : I like the game so I am biased. Old content is easier, you get echo buff (some you have to at least survive 3minutes before getting the buff and for Coil 1 you get the buff directly entering the instance) but With the new content you have a little drawback, people that used to farm old instance moved to the new so you have bit less coordinated team.

GL finding your FC, there are some specialised in PS4
