When I started playing SWTOR, in the initial beta, before launch, I thought to myself, these guys have got it right. The story is great, and you can play, without repeating sections, as a group. Grouping gives bonuses so is encouraged.
Take a Trooper and a Smuggler and starting on Ord Mantel you and your friend can play all the way through Makeb as a team. (Or Warrior and Inquisitor, or Knight and Counselor, or Agent and Bounty Hunter.) It was fun, it was cool. Get off the starting planet and you can go all the way from the home planet through Makeb and you can play with 3 friends.
Now along comes Shadow of Revan, and you have to split up for the conversations. Not as much fun, but most of the action was not in the sections where you are together. Manageable.
Knights of the Fallen Empire? Not a chance. Almost the entire story is required to be soloed. There is no real reason for the computer to even be connected to the Internet, except you are made to do so and the resulting slowdown.
This is no longer an MMO, it is now a single player game with some team or PVP play bolted on.
And the rich fully voiced story? That goes away after you get done with the first section. After that it is repeat, repeat, repeat for each toon you bring up, after Makeb it is the same story regardless of what faction you are in.
I am definitely disappointed.
