Hey Raw,
Thank you so much for the detailed guide. I must say it has helped me a lot when I just started out. I'm currently level 61, and I have had 3 occasions where I couldn't finish my GW. Just wondering, have you ever had trouble finishing GW? If you're able to complete all of your GW, may I know how did you do it? This is my current roster: https://swgoh.gg/u/icemerlin/collection/
Side note: I'm working towards unlocking 5* EP hence I got Luke to 5* (yeah I know he's bad but he was my fastest option), and I'm working on Ackbar now (just 15 more shards) before the event ends (calculated to be left with 6 hours at the point when I get AA to 5*).
