Hello!
So, today I found out that the Cybran T3 mobile anti air (Bouncer) units can destroy shields belonging to the same player. If you park them under a cybran shield and let them shoot at incoming air units they will inevitably shred through your own shield, especially in larger numbers. I've done some testing, using non-attacking enemy air units floating above my shield. Every time they switch targets after overkilling an enemy, the rockets that are still in the air explode damaging the shield. 10 of them take just a few seconds to eat through a cybran shield on its 3rd upgrade.
Is this working as intended? Should I be careful from now on to separate my mobile anti air and my shields?
I've demonstrated this in the replay I've attached, should anyone want to see this in action.
