I did not consider the use of closers without using an opener first. Thusly why I posted it here.
It turns out I can't do this the way I would like to. Ideally, I could prevent Jenquai from (ab)using their advantage by limiting openers and closers to only working on small WPs, but that's not possible.
But I'm not giving up entirely on placing limits here, I'll just limit the range of Terran and Progen WP openers and make them more expensive. They have to build a gate, after all..
