So there's obviously been a lot of frustration with the Galatic War changes, especially from f2p and new/low level players. This post is intended to be help for players just starting out, or those who have just unlocked Galactic War, but are still at a lower level where it's tough to complete all 12 battles. These tips are based on my own playing experience and my daily browsing of the forums.
Think of this as what I would do if I had to start over from scratch as a f2p.
I am f2p and I've completed Galatic War pretty easily both times since the change. The squad I run is:
Barriss 4* (L)
Geonosian Soldier 3*
All at gear level 7 minus Barriss.
So obviously Barriss and Lumi are not easy to get right from the start for f2p. Don't worry about that. Instead focus on the strategy of this group. I run with 3 healers and 2 heavy DPS, single-target attackers (Geo and 86). The three healers allow you to smartly time your heals so there's always someone with a cooldown fully reset and ready to heal the party. I think with the new GW format, this is a good way to go.
With that strategy in mind, how should a starting f2p player maximize their start?
1) Focus on farming the Jedi Consular
"JC," as he's referred to here on the forums, is a fantastic character who will help you even at the higher levels of the arena. He's also one of the easiest characters to farm without the need of GW. Focus on getting him starred and geared first.
2) Use your cantina shipments to unlock Old Daka
This is a toon I still haven't unlocked, but I wish I had focused on from the start. It will take a little while, but you get cantina energy free every day. Why not double up and farm the Geo Soldier at the same time? (He's a great character as well!) Daka unlocks at 4* and is another powerful healer that can also help you with Dark Side missions.
3) Farm Talia
Also a very easy-to-farm toon and she has an extremely powerful heal. If geared and starred up, she hits very hard. I'd focus on her once you get JC to 4*
4) Pick a high DPS attacker to focus on
A critical piece to focus down the most dangerous toons on the other team. There are several good options that don't require GW. Sidious and IG-88 can be purchased from arena shipments, Geo Soldier and Luke are farmable from some of the first cantina missions.
Yes, this process will take some time, but if you create a plan early on, you'll have a nice team by the time you're at a high enough level where you should expect to finish GW every day.
I hope this helped! Remember, this is just my collection of thoughts and is by no means the only way to play!
I'd be interested to see what other experienced players would do if they were starting from scratch. Share your thoughts!
