I personally am going to enjoy collecting characters, building squads and not worrying if my droids can't take #1. There are more parts of this game then arena. Raids a very important and Droids are a very easy P2 team for HAAT. And I'm on a young shard, but still take top 20 with my droids every day.
*shurg* not butthurt. When they do eventually get buffed, you'll have them. And IG-88 and B2 are very useful in other parts of the game, so really you're only looking at IG-86 being dead weight.
