I dunno if swearing is allowed in the tags so I refrained from it.
Hear me out - there's distinctly a class that's "missing" in the theme of the game. Well, it wasn't missing so much as displaced - that of the warrior who uses fist-weapons. Sadly, while Warden used to fulfill this role, it doesn't seem like they do anymore, since their shift towards focusing on spellcasting pve/melee pvp. Fist weapons might as well be stat sticks now for caster classes.
However, simply adding in a "monk" class wouldn't really work, in my opinion, as the setting seems to borrow from an entirely different set of flavoring. Unlike the western european part of D&D where the eastern flavor of the monk was a neat, exotic complement to the rest of the game (besides, there was something kinda bad-ass about being able to kill a dragon by karate-chopping it in the skull)
But this isn't D&D, at least not traditionally. This is very heavily Russian. And to that end, I feel like if there was to be a fist-weapon class that would take full advantage of the flavor of the setting.
The Wrestler. Kanian Pugilist, Gibberling Scrapper, Xadaganian Grappler, Orc Brawler.
Light armor wearing class. Primary weapon type is fist-type weapons, though other dual weapons can technically be wielded... just the Wrestler will never use them. Rubies improve Wrestler damage if they are using a fist-type weapon, though. Secondary weapon is a bow, though all ranged attacks are the wrestler literally throwing arrows at the enemy.
Resource is stamina because I'm not currently feeling creative.
Roles: Damage, Tank, Crowd Control
Example abilities
Palm Smack - Smacks an enemy with your each palm for X/Y/Z damage each strike.
Takedown - Push an enemy into the ground, dealing X/Y/Z damage and stunning them for X/Y/Z seconds.
Dart Tossing - Throws an arrow like a dart at the enemy, dealing X/Y/Z damage and generating enmity
Grapple - Force an enemy to drop everything they are doing and grapple with you. Bosses instead suffer a slowdown effect and the Wrestler is dragged by them.
Racials
Kanian - Gut Punch - Punch an enemy in the approximate gut, dealing X damage and preventing them from casting spells for Y seconds.
Gibberling - Triple Special - Perform an elaborate and showy triple attack that deals X damage and disorients an enemy for Y seconds.
Xadaganian - Dirty Deed - Apply pressure to a sensitive area with your knee, dealing X damage and slowing an enemy for Y seconds.
Orc - Jaw Punch - Punch an enemy in the jaw, breaking their teeth, dealing X damage and Y damage over time for Z seconds.
It'd be great, wouldn't it? Granted, I don't know how much communication there is between the localization devs and the devs in Russia, so for all I know this suggestion is completely pointless. Still, it was fun to write. Definitely would be better for this game than a standard warrior monk would be, wouldn't it?
