No overdrive. Really would have helped if I had more metal from Overdrive. Lots of wasted E on the grid, especially the geothermal.

Needed more Aspis for the shieldball quite honestly. Just looking at mine, the amount of Felons I had could have discharged really fast into his.

How do I engage a shieldball with my own if his is larger than mine? I didn't really go all-out Rackateer spam to pummel through his Aspis, which was one way I thought might work.

Do I need more Aspis and Thugs in my shieldballs? I really don't think I had enough Aspis, but not sure about the Thug. Would Thugs have worked as meatshields for Shieldballs?

Probably could have done some smaller raids. I think making a smaller ball of 5 thugs + 1 felon + 2 rackateers would have worked for the south side of his base.

Didn't really do much rebuilding once his attacks went.

Could have done some small raids, especially NW as my shieldball would have gotten in his way if he attempted to reclaim it. Also, he had to deal with the planes.

Could I have won if I pushed his base once his shieldball went on raids?

Lots of excess again.
Didn't E stall too hard this time around though.

Summary:

Learn to be shieldball with my own shieldball. With help from Shockley/Thunderbird if needed.
Stop metal excessing
Overdrive Mexes for more metal.
