This came to me as I was trying out my new Acer Predator PC and using mouse-and-keyboard micro compared to controller clumsiness. Mission 11 is hard not just because of your rough start, but because if you don’t cap the control points quickly you’ll end up losing. But that’s where I got an idea: you don’t NEED to full-on cap them immediately, just keep them out of Banished hands.
As such, using Jackrabbit micro should help you de-cap the points and buy you some time. It’s hard to pull off, but it could help people who are trying to beat this mission on Legendary.
