Perhaps? I'm not sure how you can say:
Man, this is going to be like TOR where planets don't change. You're right, those 8/100% of the planets don't really change much in their storyline. Man, it also sucks that there may be a chance that like 60 of the over 6000 planets we have, may not change. Whatever will we do with that 99+% of planets?! :p
This game has never allowed players to take any action they so desire, there's always been constraints in the past where an admin would disallow something, or times when rules disallow, or when in general something isn't allowed for feature reasons. With so much of the galaxy free-reign, I have 0 regret seeing a few places being kept as safe-havens to have to explore/have quests/other future features take place. There'll be plenty/are plenty of new planets already out there.
