When I play I am always working to cause my opponent to collide with me. If they hit me I'm getting actions, they aren't, and they lose the ability to focus fire my ships. Most people I play with don't seem to do this nearly as often. Is this psychological, people don't want to crash in either direction, or is it that engineering crashes isn't as strategically helpful as I think it is.
Either way, it's given me a pretty strong aversion to higher PS pilots. Anything over 6 is just too high.
