From the 5.050 release notes
Spire Shield Guard Posts (the normal ones, not the Core ones), in honor of tying for second in our first "Aim The Nerfbat (AI-Side)" poll, have had their health changed from 56M*mk => 28M*mk.
Galactic Sandpaper Incorporated has already filed for bankruptcy.
Thanks to the poll participants for the feedback.
That's a good deal less than the AI forcefields (which are about 42M*mk*). Are you sure you want to nerf it that much?
Still, even at about half health, they still have more HP than human forcefields (20M*mk)
Also, I don't get the sandpaper joke.
* When looking this up, I discovered that the AI forcefields did not get adjusted to the proper 2.something ratio from the last balance pass of human forefields, thus AI forcefields have sort of a weird Mk progression
