I understand completely. It's just this proposed rule doesn't make alot of sense to me. On a symmetric core the CG is basically useless, so the rule won't have an major impact, other than forcing people to redrill balls. But on an asymmetric core, wouldn't this proposed rule make it alot more difficult to lay those balls out legally, and still have freedom getting the desired reaction? I am no layout expert by any means, but this is just how it comes across to me.
