Architect Archive

I see bits and pieces of info scattered around, but I was wondering if anyone could summarize some of the more certain things that the patch will change. I hear experimentation, but how exactly? Will it affect current units? Should I stock up anything before it hits?

And anything else that affects us on the test center..

I've started leveling an architect on the test server, so I can find all of this out myself.. but any info now would be greatly appreciated!

Thanks

Dont stock up on anything. Current harvesters should stay as they are.
