I would like to join in the very few brush supporters, especially the Octobrush. This may be slightly biased due to my personal preference, however, I would advise you to take my rants into consideration, for I can assure you that there are many professionals that share my views. There are three different positions a team could be in: where you are pressing into their base and basically spawn-camping, where you have established a foothold relatively equal to the opposing teams, and when you are practically being camped yourself.
The brushes are one of the most reliable weapons for the former two. The squid beacons allow easy access to great vantage points for other weapons and a safe super-jumping position. They are one of the most underrated subs in the game. The Kraken provides an undeniable advantage in almost all game modes. They are almost a guaranteed capture of the tower or kill of the Rainmaker. They are the quickest killing weapons bested only by the gals and rollers/chargers, and the last two are debatable due to their charge time and wind-up. Their sadistic range is made up for by their specials which generally grant invincibility.
Also, their ability to become the quickest rollers in the game allow an easy way to escape from any fierce competitors. Brushes can easily dodge two or three opponents for a while, not only providing a distraction in which your team can carry the Rainmaker further, ink the splat zone, or run the tower, but also giving the brush an easy exit to splat another day.
It is also the absolute perfect noob weapon. They come into the game with little fluency of the controls and even worse accuracy. The brushes provide almost 180 degree coverage and at least a trade-off with kills when snuck up on. They don't need to be in the front lines brawling the level 50 with a .52 Gal, but can instead hide and surprise them when they kill of your front lines. Combined with some mid-game gear like Ninja Squid, it makes a powerful ambush weapon.
I'd say one of its few flaws are that they aren't all that helpful in Tower Control. They make quite the melee weapon, however, they should rank low on the TC list due to their range. It is not nearly as dangerous as, say, a Luna Blaster, because you can't splat the top of the tower as efficiently unless if you drop from above. I would drop it lower, possibly a B-.
Overall, I think the brushes should be bumped up to at least a solid A Rank if not further in Splat Zones, Rainmaker, and Turf War. I am personally an S+ Rank that can vouch for the usefulness of (most) brushes, and definitely the Octobrush. While other weapons may have superior range and fire power, none of it helps them if they can't catch you or react quick enough to stop you.
