So, I've searched a bit before posting this and found this thread:
http://mwomercs.com/...ress-r-anymore/
The thread is from the time when the mentioned warning became a part of the game. Everyone was able to hear the warning, no cost limit or penalty. Hence, it got removed. There were two suggestions in that thread:
1) Add it to BAP
2) Make it a module
Both of these received a good feedback as a cost to get the warning back. It probably didn't make it back because making it a module would make it a great module for scouts (darn bug-named mechs are already annoying) and adding it to BAP would mean a huge buff to anyone already using it.
I'd say make it an extra module of 0,5t and 1 slot OR implement an (Advanced) ABAP; 2t, 2 slots. 2 tons would be a big cost to those who would want BAP only for the warnings. That way any scout would be able to choose between more map awareness and tonnage.
Also, you wouldn't get any warning if the mech targeting you is inside an ECM bubble.
I know there ain't such a thing in the Tabletop, but feel like it would be a good addition to the game. How many of the game's playerbase is actually really here because of the original tabletop?
