The game doesn't teach players how to play. It is the game's fault. Tutorials on moving with W,A,S,D is laughable.
I don't vote kick people, but if a HM FP group can't kill a normal boss in 3 attemps -> Force Cloak -> Exit Group
I can't teach people rotations in a FP run, nor compensate for their bad gear.
There are lots of players like this and you can't spend time on every one of them. Same goes for operations. In the end they waste other players' time.
This is an MMO. Join a guild if you have no idea what to do. This wasn't my first MMO, had played and still playing Eve Online, but it was so unfamiliar. Joined a guild, got the ropes.
If you don't want to join a guild for any reason such as being shy, "solo" person or "don't have time", I'm sorry but an MMO isn't a fit for you. RPGs are a better fit.
This isn't KOTOR 3, yet, so wait long enough and it will be.
