Warrior General Games

So far I am pretty confident with my build.
But I have not yet spent any points in SA though, which I have neglected on purpose.
What I'm wondering, is what is the suggested levels to start pumping points into SA's?

Don't even start until early 30s. Some wait later if they're really slow building

actually, Change Direction could be of some benefit in the early 20s if you have CE and AEQ that boosts it

Well, it depends how soon you want to be fully competitive.

Hmmm ok. I was just looking for a rough level estimate and I think I got it.
Thanks.
Another other advice is welcome though.
