I am an unreconstructed Opel Blitz fan for 4v4 . I freely admit it
I would run out my Opel trucks and paint our sectors yellow on the mini-map. The team benefitted - I don't think anybody ever thanked me - but they rolled out their heavy gear whilst I strafed - and waited for the Tiger.
Then the first nerf: Strafe went to pot. Then the second nerf: only I could benefit from the yellow sectors - in theory. Now, it seems, even that was incorrect.
I can only imagine the tool tip to which the OP refers, harks back to halcyon days gone by....when an Elefant was an elephant in musth...to be approached with extreme caution. Its psychological effect was as dramatic, as an ISU 152 nowadays is.
