Reading comprehension much?
Fast Track is not the one thing that makes it TOO good, but banning it
would bring it back closer to other corps, and wouldn’t really kill any
other archetype. I think Fast Track is at its best in Astrobiotics, and
really isn’t necessary in any other corp deck, and therefore is far less
aggregious than killing something ubiquitous like Biotic Labor or
SanSan City Grid.
