I have not played around with Neinzul Enclaves since the most recent changes, so I started a game in order to find out just what they could do. I was particularly interested in their new drones, so I unlocked all the Mk II turret tech I could and the Mk II Enclave and put them to work. A few hours in and several planets conquered, here is what I learned:
1. Two Mk I and two Mk II Enclaves, put on free-roaming defender mode and constantly producing drones, can overwhelm most Mk I or II worlds pretty easily. If you want to clear Mk III and IV worlds, you'll need to micromanage a bit more. Set the Enclaves to Attack-Move and use shift to set a course to the various guard posts.
2. Mk I and II Drones can destroy fortresses in just a few minutes. I was surprised, too.
3. When I added Mk III Enclaves and Drones, I was able to take Mk IV planets with 200+ defenders, using FRD.
4. Drones work very well for wave defense, especially since I have so many turrets to support them.
5. I can defend a lot of planets, quite heavily, when I have mk I-III turrets. It lets me focus on attacking without much fear of counterattack. Yet.
6. I'm not going to have much more knowledge to spend, and I'm considering getting Mk IV Enclaves because I'm having so much fun with them. I don't know if that will doom me on the Core and Home worlds, though.
I'm interested in other people's experiences with Enclaves. What have you used them for?
