Amputator and CIV need damage to be on par with the Combuster
Leviathan Blade and Final Flourish need damage to be on par with the Acheron
Shard bombs needs to mechanically evolve kinda of like the Alchemers with more shards with every star level, and at 5 star have 2 rings of shards instead of just 8 individual shards... I do think knockback could be removed or more heavily reduced for the Salt and Sun shards with more emphasis put on flinch. Along with an Elemental variant for killing undead...
Tortogun charges need to be a fixed landing pattern with the center crystal landing on the monster targeted.
Spur line swords need a total overhaul, aside from the flashy effects it really has nothing going for it.
Magnus type guns need knockback of enemies not be reliant on which way the enemy is facing but the path of the bullet... so shooting an enemy facing any direction carries it along the path of the bullet... (may need a damage nerf to compensate for this buff)
Antigua guns need to fire one bullet for a button press and another for the button release resulting in still 6 shots but only 3 presses needed to use the clip instead of 6.
Catalyzer tags should be set off by any charge attack used.
Also realign all low star equivalents with the high star lines. Troika buffs should also show for Thwack hammers and Hatches, Cutter buffs should show for the Red Saber, Magnus mechanics for the Punch and Pummel gun, Spitfire should deal status on the regular shots like the Frost Gun, Super Stun Gun, and Zapper
