Will you need rise of the hutt cartel to keep playing swtor
just need to no if i have to have it or not
No. You can keep playing the other planets, just can't Goto makeb. Leveling to 55 can still be done in pvp war zones.
You will need The Rise of The Hutt Cartel to keep playing the game. This is because it brings up the level and adds a new planet to the story content. The more you uncover, the more you continue playing the game.
