It's fun at the moment because it's new but it seems more like a simplistic way to get people to just have a big roster for the sake of just having them and get specific toons rather than anything challenging which requires thinking and a strategy like the raids were when launched.
The fights are waaaay too easy and repetitive. The only challenging part is having millions of combined GP which is just gear and shards you farmed or bought. It doesn't feel like we are reliving the Hoth battle, at all.
I'm hoping maybe in Phase 6 we actually fight something new and interesting instead of more tie fighters and snow troopers in fight formats we've seen for years already.
