Good:
1) Selen toggle - requires explanation it not.
2) MAA buff - same as 1. Good that now they are of any worth.
3) Naval HQ nerf.
Bad
1) Buildings HP change - this is the area where all factions should be equal. Reason being is: Why should I, as UEF, pay for just 1 TML to kill your T2 HQ or T3 pgen when you have to pay extra 50 mass for the launcher AND you have to build two tacs? Now don't tell me it's so Cybrans would use stealth more because a single scout will reveal everything. Bah, I don't even need a scout! When your T1 land factory goes dark, I know you went T2 so I'll TML it ASAP.
I agree with nerfing naval factory's HP but that is the only part of HP changes that I agree with.
2) T1 bomber - I am fine with higher cost because bombs were buffed. But removing the radar makes the bomber blind. Before, I could send one out to an enemy expansion that had no AA, just a few engies, and I did not need a scout. I'd micro the bomber to fly over the area so I see where the engy is from afar and I can turn the bomber to kill it on the first pass, without the need to fly over without bombing and then come back as it gives time to the enemy to scramble fighters and kill the bomber. Now I need to send a scout (extra 40 mass that will be donated, should the operation "Engy Kill" fail) to queue attack orders for the bomber. Do you ever see a real life bomber flying after a scout? No, because the bombers have radar of their own and they can find the targets, even if they do not know their precise location.
3) RAS nerf - Sure, nerf energy. However, do not nerf mass because at the time someone gets RAS, they will need extra mass for production. Plus you paid 150k E and 5k mass for this venture, better see it pay off well and 8 mass is not good enough a payoff.
Uncertain:
1) Lobo - I do not see this being a significant impact, theoretically or practically so I have nothing to say.
2) Fire Beetles - Saw them just a few times being used, not enough to conclude anything.
Suggestion:
Revert the changes made to structures and RAS/ARAS. Focus on units and let structures be.
