Ironically the changes made after the player/dev gamma conference call has swung too much in the difficult to kill direction now. Having reinforced building lose a % of their functions is an excellent idea. If its made that they lose all, there needs to be a way to repair them temporarily ... (Not an easy way)
I don't want anything made too easy in the game. If the game mechanics allow a relatively new, but determined corp the ability to at least try and settle Gamma, then I think it's a good thing. But to make bases virtually indestructible is not in anyone's interest. They should be hard to kill, but not impossible. I personally was hoping more buildings stayed destructible outright, and terraforming charges had retained some cost to them, but that's me. We are seeing the effects of this last change now. Hopefully the dev's will balance things a bit in the future. A game like Perp that is constantly updated needs constant balancing, it's the nature of the beast and I accept that.
Disclaimer: I don't think any current base is indestructible, be it ours or Chaos, and I'm sure we are both going to test that soon ... But I do think it may be a bit harder than it should be. Ultimately base defense should succeed on the human reaction and good planning, not automated systems; ie you wanna live on Gamma you need to be able to defend it.
