In all lines of sword: At each level, you get your damage increased and at Level 10, you get damage increased even more. I feel this is essentially like an Attack Damage Increase of how hard you can swing the sword.
In a similar respect, As much as I'd love to have an Movespeed / Increase bonus of Low and Medium at Level 5 and Level 10 respectively, I cannot. I feel a similar principle could, and should be applied to swords. Let damage bonus be not be attainable through leveling up a weapon and only though special bonuses (Unique Variants). Otherwise I would like to see some Movespeed Increase bonuses for bombs of Low and Medium at level 5 and level 10 respectively
tl;dr Swords still too OP; nerf feller.
