Honestly...what were you expecting? Have the expansion unlocked without doing the story? You played to 50, you know there are trials and dungeons in it.

Get a new fc if you don't want to pug. You'll have new trials and dungeons in Heavensward as well to do, so keep that in mind. This IS an mmo, you will need to play with others.

And yeah, all the required trials/dungeons are easy to run through. Don't expect that to carry over to the expansion, however.
