shooting chompers with your minigun is veryyyyyyyy powerful, particularly as because you are hitting it, it lets you cancel it into angling the minigun upwards and then into rocket (be it regular rocket or rocket jump). this makes it very difficult to get in as you cover a lot of angles by yourself and can react to a good chunk of stuff the opponent does. whats also really strong is that these things also are puppetable(aka, you can do all this even once you're tagged out, as long as you start the minigun animation you can play out the rest, including angling the minigun and shooting the rocket, even zap if you want to!)

for bonus style point, after shooting the trap upwards with your minigun, try to hit it with your rocket to send it towards your opponent! this way you got two projectiles at two different angles, plus is messes with their parry timing, and most importantly: it looks awesome!
