Sentinel is easily my favorite class for the weapons and how unique this class is. We have double sickle scythes, twin bladed swords, a flipping barbell hammer like weapon and other different weapons. I am impressed this class has a lot of variety in weapons and wish the others were more unique.
Sorcerer has the potential to be an awesome class for weapons since we only know one so far thanks to

Quickshot seems to have an idea on having different kinds of guns for battle and even have different kinds of projectiles like

Smasher kind of surprises me with the variety this class provides. They have hammers, axes, clubs, hammers and other kinds of good smashing weapons. I thought we'd only see like one kind of weapon on our senseis, but surprisingly quite a few different weapons.
Knight so far seems to have simply swords. Ambush has a giant green blade and the potentially named Wildstorm who maybe the air sensei could be a knight and also use a sword. I hoped to see other Medieval weapons in this class like flails. lances, maybe some shields and other weapons in those ancient times. I am sad to see they just got swords so far and hope they change it up soon.
Bowslinger hasn't got much exposure, but even this class still has a chance to shine. They can have crossbows, hunting bows and other unique styles with unique arrows. I feel this class can have some cool weapons, but not too many obviously.
Swashbucklers have no real official images for senseis yet and I hope to see more than just small swords. There can be cutlasses, scimitars (I think Bad Juju should have these) and some other ideas for this class. I only put it this low simply for the fact we haven't seen much of it so far.
Brawlers are pretty simplistic on paper, but they can actually be surprisingly interesting. Maybe they can have martial artists, brass knuckles, boxing gloves and other unique weapons for these brawling combatants. I hope to see a lot of variety in this overall straightforward class. Crash Bandicoot and King Pen so far show potential in this class and I hope to see some cool brawlers.
Ninja has criminally disappointed me so far. We have Tae Kwon Crow who has throwing stars and the mysterious unknown ninja seems to have golden throwing stars. Where are the kunai blades, smoke bombs, kamas, nun chucks, and other ninja weapons there are? This could even be the class for bombers like

Bazookers are easily at the bottom since we have seen practically nothing on it, no senseis have been confirmed yet and there may not be too much you do here. I mean yes cannons, bazookas, rocket launchers and missile launchers can be used for this class, but I don't know what direction they are going yet since almost nothing has been done with this class atm. This class better be astounding to show none of the senseis whatsoever for this yet.
So these are my thoughts on the classes so far. I like the idea, but the concept has so far been too predictable, limited and generic for the weapons they can use and so far show little to no variety the senseis can have. I am however glad to see there don't seem to be too many brawlers or smashers so far as that could have been an easy shortcut for the creators to take and have made some pretty cool guys so far.
