I would love Mustafar to be in the storyline. With all the lava and destruction. Now what would we do there though? Who would the enemies be?

yeah i agree maybe in update 2.4 they can add dabobah, which can be a wasteland for fighting

How about it can be a pvp world, for people who love pvp, this can be in update 2.4, where maybe (50s and higher) can fight each other. Sounds pretty fun

As the PTS public test server, you should be able to test everything out. Such as all crafting abilities, gear, weapons, etc. The cartel market should be open and you should be able to have unlimited coins, to test new gear out, and see if you want it on the regular servers. I think we should add on to the testing on the PTS to see new things.

As we all know, Dagobah is a world where Luke finished his training. Dagobah should be a new world for all players 55-60. They all have a new storyline. For example Sith Inquisitor, they should be looking for a lost jedi artifact, that is very strong with the force. So that's mainly all, but we should add on to the Dagobah world.

I would tell someone close er to him to stop the experiment ASAP

Yeah ill add on to that maybe another new maybe flashpoint or operation is where you can be fighting on a speeder and if your someone who does close damage you can jump from speeder to speeder.
