I heard SMACs needed a survival buff. I gave them a survival buff. End of conversation. If i give it an auto repair ability it would negate the Cradle AND MORE IMPORTANTLY the repair structure. So if I did everything you said it would have an auto repair, fighters, and a ton of health. Why dont I removed the entire defensive tree from the UNSC and just give you SMACs and an I win button.
As for the Halcyon. I have taken what you have said and talked to Rovert and have talked to other testers. The Halcyon did receive a buff due to the health boost. However, if you had say 4 more thanatos classes Im hearing that the alpha strike is still much higher and is able to take over halcyons. This to me is balanced as when you look at the population or supply cost the Thanny sits at like 12 and the halcyon 15. I will continue to look into the matter to double check the halcyons role and make sure its not OP or the new spam target. Thus far I havnt heard that yet. Also keep in mind that the Halcyons nuke missile is a 110 or 120 second cooldown. where as the thanny as one that sits at 70. for Two MACS. So in 70 seconds it does 6000 damage and the halcyon does 4500. Thats negating the thannys missiles which would add around another 700 at least.
