I think you are missing the point of the improvements to these characters. Not only are they trying to stay true to the actual popularity and importance/strength of these characters in the saga, but they are also opening up the game to a less consistent META. Now in the really old shards, the meta is varied allowing you to choose multiple avenues to be a top tier player.
For the past few months, the meta was CLS...CLS...more CLS and then JTR and nightsisters took over a little bit. Now you have the option for CLS, Empire, Sith Nightsisters, JTR and GK Zarriss is still decent. Even a zzKRU lead FO squad is a threat. They want to allow everyone to use different factions that they enjoy, which will make the game more diverse and enjoyable for everyone whether you just started, or if you’ve been playing a long time. It’s a great change and with the upcoming sith raid rewards getting into the mix, Traya will soon be a strong competitor as well. You may not like having a shard full of empire, but that doesn’t mean it’s a bad thing.
I’m not sure why you think changing to an empire team will exacerbate the problem, because it won’t. You changing to empire in your shard is like throwing a pebble into the Mississippi River. The effect is minimal at the most. I knew I needed to prepare for R2, so I starting working on Empire a while back. This update made my life so much easier. I went from struggling to stay top 50 with Phoenix to being top 20 and for a few days until zetas were applied, i even hit top 3-5. When I’m finally able to get my first zeta, I’ll be back up to the top with my squad too.
You as a player have to be flexible enough to be able to use all the characters you have for what they are worth. Squad arena is only a small part of the game. I’m working FO now for BB8 and I’m enjoying that. They are another tool to increasing my roster, same as with my crew members. I worked on maul for a long time and now that he’s done I’m enjoying the scimitar a lot more.
The point is, not everything is about squad arena and you have to be able to change in order to be successful both in squad and the other aspects of the game. Keep an open mind and I’m sure you’ll be able to counter the empire/sith craze soon enough.
Some solutions for your shard that are also f2p: Zinn resistence team with BB8 will be tough to deal with. Rebels still work really well when using Biggs cuz he’s a nightmare without death trooper to daze him. Chaze is another option and one that you’ll eventually want to work on. Even getting Shore trooper, Death trooper and Krennic when they unlock for you will give you a plethora of options just in the empire faction to be more competitive in your shard as well as in the other game modes.
Also remember that getting these character will help your guild in territory battles so its almost hard to mess up. I’m currently working on ShT and DT because they are going to really help me in Squad arena and they are 2 of the lesser owned characters that are needed for TB so it helps my guild a lot. Focus on your roster in every area of the game and keep your head up, you’ll be fine. Also mods are a huge part to your success. Understanding them and making your team fast enough will help tremendously regardless of which team you choose to use.
Btw, I started on Oct. 28th 2017 so I’m no veteran. I’ve just had a lot of help and i read a lot. Hope this helps
