Nobody designed that. Players liked it, it stayed, and now every rebuild copies a limitation from 1978 on purpose. You feel it most with the last two. They move at roughly triple the pace of a full formation and they are the reason plenty of waves end one alien short. The bunkers erode Four of them, and they are not shields with a health…
