Bit late to the party on crying nerf.
And, telling people to just build a counter team is not the most feasible thing since the Empire Teams are not the most accessible. Who knows when the next Emperor event comes around, and surprise surprise you need a geared rebel team to compete in it (or clones, but most people don't have them). Vader, also takes a very long time to get starred up, F2P or not. Rebel teams with Wiggs should never have been developed in the first place to be so crazy. But, once it was there it wasn't too feasible to just nerf them since so many people invested in them. Heck, until ships update 8 or 9 out of 10 teams in the top 100 were wiggs, and many with Lando too. It's still about 7 or 8 out of 10 in my shard, but it is what it is.
Zeta shards are great and all, but take forever to get so shouldn't have to wait so long to be able to match them.
And, also telling people to use the new toons is not feasible at all since only the really heavy spenders (At least hundreds) have access to them right now.
I also went droid, and it is tough facing them. I finally managed to get to rank 12 in my shard today before using up my daily 5 as I was lucky enough to find weaker wiggs teams (and 1 jedi team) to attack for a change. Finally getting Jawa Engineer on 7* helped too as he is less squishy. With Droids I find it best to focus fire on Lando first, then Wedge, and then Biggs, and tanks last. It sucks I can't use AoE, but it is what it is. If Biggs fires his overpowered ability with the double assist then I pray it is on B2 or HK47 as they are the only 2 that can survive after it.
