I think rather than Bomb, Mines would ideally be replaced with something like Wipeout Fusion's Power Snare, which would be wider than a single mine but not as wide as an energy wall, and would hover in place like a bomb rather than falling to the floor like power snare did in Fusion iirc. Ideally it'd be as tall as single mine is currently and do an amount of damage between that of a tremor and of a missile without causing weapon slowdown, instead calling a function that causes your ship's anti-gravity generator to fail briefly (I actually triggered something like this once while testing weapons in splitscreen), resulting in you bottoming out (or potentially falling down during a jump and getting recovery droned, missing out on necessary height for a barrel roll, scraping along the floor on an incline/decline, etc) which causes an amount of speed loss that can range from minor (bottoming out in a relatively flat, straight section would barely be noticeable, which means if the power snare is blocking a weapon pad/speed pad you can still safely choose to tank it and not lose out too much) to significant (getting recovery droned because you hit a power snare over a jump, not being able to benefit from pitch/glide-induced bounces that would otherwise enable you to wall scrape with a greater margin of error through a tight technical section). What sets BallisticNG apart from Wipeout with regard to 2159 in particular is how prominent pitching is as a mechanic. Racing lines are truly 3D and a power snare like weapon would reward those who have mastered pitch control and have a refined understanding of race lines in 3D while still being accessible to less experienced players as a fire-and-forget weapon that can hit people behind you without being disruptive in the way that mines currently are.
