To answer some questions:
1) I use quickstart, just Shift+S on scouts and you get 100 supply( not effective, some may say, but I don't think so)
2) Dindn't realise that the capital ship condition means 1 extra supply of units.
3) Give me one good reason to spam corvetes, and please convince me. I like to open with the Kortul Devastator + colony ship.
I had in mind a double Kortul Devastator opening, but now I realise it's usless unless you are going 1v1 hard on someone which is not vassari or is Vassari and it's not building Kortul Devastator. They a bit OP in the beging ( virtualy infinite shields ), at least vs the patrols near uncolonised planets.
PS: if you have some good openers i'm all ears.
