You can go on:
Adventures
Fight Bosses
Level up

as you PROGRESS THROUGH THE MSQ. Not that hard. Again, if you come into an MMO late, you miss the early content for the first time and get the watered down version. It's not the end of the world. Deal with it.

Seriously. The entitlement is strong with some here. If you want to do Shadowbringers as it comes out, log on, level up like crazy. It's not the most difficult thing in the world to get a character to 70, and with the 900 genesis per week, you can get really good gear, run the alliance raids, farm the coins, and have a FULL 400 set for the expansion. Hell, just by running Orbonne you get 390. So at most it will not take that long. You even get an exp boosting item for preordering shadowbringers. Like...Jesus christ people.

I'm not salty about missing out on Creator, I chose to join the game midway through it. It's like being mad that you can't fight the final boss because you haven't done the tutorial of a game. "Waaaaa, I wanna fight Gwyn, Lord of Cinder!", "Okay, but first you need to fight Taurus Demon." "Waaaaaaaaa no! I wanna fight him RIGHT NOW!"

Essentially, that's everyone wanting it the easy way.
