My post was directed at random artillery, which I really like, but yeah set minefields are useless...player-set mines would be interesting though, but they'd have to be issued in VERY limited numbers to prevent CoD-like spammage (such as almost every member of an American team spawning with German Springminen (nicknamed bouncing betties by Americans) ...argh...) plus they'd have to be historically correct to whatever was used in the actual battle
and the don't-go-off-the-map minefields in RO work perfectly, I see no problem with them
