I haven’t played in a while, I found it’s usually about spreading their damage over your shields while trying to keep your damage concentrated on one of their shield zones, then targeting the shield generators.
If all else fails, try spinning, that’s a good trick
I saw a bit of those on stream and thought maybe the time affected the quality of the result… but no. It’s just filler shit to get your space dragon speech spell or whatever. Then the enemies are all bullet sponges. It all seemed very transparent and very familiar.
