Hopefully this won't derail the actual subject at hand but....
When it comes to mines I'm usually the clumsy putz waltzing into them.
Which is probably why I regard them as a handy defensive tool, and why I've taken to playing covertops to spot them. I don't doubt upping the cap would be very bad all things considered - give anyone a handsfree way to score points and you just know it'll be abused.
