You can squash people, roll 'em over, use the sub, and the carbon roller is best, it is the fastest and has a burst bomb, if you have all gear with damage up abilities, you can knock people out with one single bomb, if you use the roller with seekers, you can hide and throw subs from far away so if you are trying to reach something, you can get the people hiding first, also when you get your special up, it comes with a seeker rush, so anyone hiding can be spotted:) ;) also if you find people on the map, and you are using the tempered dynamo roller, you can use a seeker to seek that person on the map, and if you didn't get them cause of a "wall", you can use your special to get them through the wall, also the splat roller is good too, you can use suction bombs to reach from far away, and if people run your way you can squish them and if you use this roller in rainmaker, you can use your special for the rainmaker to break the shield.
