This game has fantastic weapon balancing. The Splatroller might look "OP" but it is only for up close melee attacks mainly. The Splat Charger takes a little bit to fill up so it is vulnerable. The other two are great because they can take both the Splat Charger and Roller out, but they can be taken out by them. Every weapon can be taken down by every weapon and they all have their weaknesses. If you still honestly think the Splatroller is OP I don't know how you can even think that, it can be taken out so quickly due to its range. I got in a game against 4 Splatrollers and we dominated. As long as you keep them contained, they are easy to take out. Also not being able to customize your secondary and special might seem bad, but it keeps every weapon equal. If certain weapons had different secondarys they would be OP, but it is perfect. No weapon is OP as of now and it seems like it will stay that way
