Was fun to play, had a game with beta balance, and then did some testing. I like a lot of the changes such as splitting the shield upgrades on the uef scu and the bp reduction.
will be interesting to see how the sera regen field affects t3 naval combat, the sera BS gets 90 regen per scu, and all the while the scu is knocking a chunk off of it's cost with the +3 mass.
I think that removing sacrifice gets rid of a very interesting feature and that keeping it in would allow for some cool plays in scu combat. More than just a late game cheese option for tele-gc or tele-paragon, sacrifice preset has a ton of versatility and can be used in many situations. For example if opposing scus are winning a fight but they get too close, you can quickly sacrifice into a T3 massfab for an epic kamikaze doing massive aoe damage to groups of units (or a t3 pgen for slightly more damage but less aoe). You can support the rest of the army and squishy units like sniper bots by quickly sacrificing into a T3 shield. Or many other things really, there are tons of possibilities with it. It would probably need to be rebalanced, maybe a cost increase.
Also Chrono doesn't seem too strong, I think it could be useful against shielded rambo coms if you have absolvers, or groups of units, but the stun itself isn't very strong and does not last very long. It'll get focused down pretty quickly, you can upgrade the cheap first shield in 32 seconds if using the chrono support preset at least.
