Sounds cool, I think the idea is a good move for the traders and escorts. I find many times even having two escorts vs a pirate bomber they just fly in circles like crazy then hit you with SNAC or the dreaded Nova torpedo again and again. Doesnt take long at all to die. This makes pirates have to work together more as well.
The only problem I see is that its not easy to get everyone together. Some people just cant get escorts. Another problem I see is gunboats with 800 million credits worth of armor. Does that even make any sense? Off topic?..yes
