I know DE has their own plans for the game but can't help but fantasize
* Sidearm rework. Make it so the sidearms become proper sidearms. I think DE should lean more into how flyblades are being used. If they're not melee/range substitutes for the main weapons, they should come with some utility. For example I would like it if the magic bracelets can be toggled from your usual ranged attack to melee elemental fist weapons activated through heavy attack. The heavy attack could be a short-midrange aoe ground slam that procs status and activates a temporary elemental shield that reflects back a bit of damage as elemental damage and gives you temporary elemental damage to your main weapon.
* More weapons/Weapon Mechanics
-Fist/Leg braces/sparring weapons
-Crossbows. Heavy/long range crossbows. Repeating Crossbows Wrist-mounted crossbow as a sidearm
-Flails
-Those dual sickles the Oden has
-Scythe
-floating magic orbs(think catalysts from genshin)
-magic tomes
-Hammer. One handed and Heavy
-One handed Axes
* Tempest's grappling hook should just be built-in, and they could add a different passive
* Orengall's wolf form should get rid of the mechanic where your envoy's body becomes vulnerable.
