Couple Questions from a Noob (Specifically GW related)

For GW it is important that you have good healers. I am a huge fan of JC for GW. His heal has an extremely low cool down once leveled which will help you immensely. Since you don't have Old Daka, Luminara, or Barriss, Talia might also be necessary. That being said any tokens you get should be put towards Luminara, she will make GW a lot easier. From what I've heard both JC and Lumi are important for the Yoda event (I am level 70 f2p but didn't have enough 5* Jedi :o )
