Many posts claim that the roller is op. I would say that is wrong.

The roller is the easiest weapon to use no doubt, and yes running people over with it does instant kill, and yes it is fast. HOWEVER. It only kills whats right in front of it, and its splat takes a long time. If you move around the roller they have to stop to turn to and do the long splat. Run AROUND the roller or above them if you can, and they become easy to take out. If you’re aim is true then they should be taken out with ease. If you are charger just swim the hell away or gain high ground.

Mentioning the charger. The charger is not a bad weapon like some people are saying. The charger is a support weapon. The chargers job is to find a perch (or better a series of perches you can easily move between) and shoot enemies that are hassling your team mates. This makes it so ONE: your team doesn’t die by the enemy. TWO: your team mates are now free to paint the area. THREE the enemy has to waste time re spawning in a very fast game.The charger is as good as your ability to aim. (but yes it is bad at inking)

I would make this a read more but I can’t find the option.
