I like the special forces, strategic reserve, and homeworlds as they are now.
Brutal post breakdown from hardest down:
Eyes: They prevent stealth operations, and make sledgehammer-lobbing inefficient.
Wrath lance: Any small fleet quickly disappears. Big ones take a little longer.
Raid engine: A wave is bad news in the endgame.
Teuthida: a lot of dps, but can be countered with scout starships and/or reclamation immunity.
Grav reactor: raids will be one-way, but little impact on the final battle.
CPA post: launches wimpy cpas after 10 whole minutes. Pretty much ignorable.
The champion balance still needs something offensive for the AI, but is close to right.
Some ship types need to be looked at (Zombards, TDLs, and swarmers).
We still get duplicate scenarios.
Allied enclaves need work (should be highest priority: game balance problems are bad enough, these cause lag).
And 10/10 needs more pain dispensers.
