Got a few minutes, so I'll toss out some thoughts/opinions, both on current and recently announced changes. I mostly play Superweapon General, so that's where most of my thoughts will be.
If the SSM's replacement is going to lack an option to clear toxins, can it be given an option to hold fire on its main weapon while letting the garrisoned infantry fire? I get a lot of anti-drone/airdrop/sneak attack milage out of leaving a Pathfinder or two in an SSM in the middle of my base, and I set it to Cleanup mode to keep it from firing on whatever building is next to wherever said infantry swarm spawns. I already have enough trouble with Auroras retaliating against point blank attackers and wiping out the airfield they launched from. Maybe some kind of mostly passive structure like a Crisis Control Center that would allow a garrison of 2 or less for "security purposes" and maybe have some ancillary abilites (like a Cleanup AoE).
The new defensive options for Superweapon (deployable cores) and Cybernetics (spider nest) are awesome and I love them already.
Flares are a severely depreciated upgrade in a mod where missle-based AA has become a side possibility instead of the standard.
I'm less than super excited about Saturn no longer being able to shoot down projectiles. It's probably my favorite aspect of it. Now that the Nemesis is no longer going to be a combat unit, I'm kind of lowkey hoping the Saturn will be converted into an air unit so I can play Independence Day with it.
Really looking forward to the Weather Control Device's changes. It was my favorite SW from the Red Alert subseries. I know it's mostly for the EMP effect, but I can't help but hope it does appreciable damage to stuff other than infantry this time around.
New SDI Cannon looks really slick, but I admit I'll miss the heavy concrete bunker basing around it. It reminded me of the super facilities that Ace Combat is famous for.
Demolition General drives me up the wall. All of his abilities just spawn in at ground level, suddenly surrounding entrenched defenses supplied with stealth detection with an instantly lethal amount of damage even with Armor upgrade purchased and Hold the Line active. And their level 5 that crashes a plane into a target area can't be intercepted by SDI, Saturn, or the shield generators.
For supposedly being the faction's signature, Particle Cannon feels really weak for some reason. I get the most use out of it finishing off already heavily damaged buildings. I'm not really sure what its intended use case is. "Particles" are super vague and can mean anything from an electron bath (low damage, massive EMP) to a neutron slug (proxy asteroid impact). Kind of pipe dreaming, but it'd be nice to see the PC balanced upwards with special effects instead of just upping damage. Even replacing its current effect with a draw-your-own firestorm effect would be cool.
Speaker Towers currently count as primary base structures instead of defensive emplacements, requiring you to hunt them all down to eliminate a player. I don't know if this is a bug or an oversight, or even intentional, but it doesn't warrant its own post in the Suggestion thread.
My time's up for now, but I'm really looking forward to whatever you guys end up doing with it.
