They should keep their current function, but with a shorter cooldown on Stasis Shard generation, and additional effects while you have Frost Armor. Tectonic Harvest: increased melee damage while you have Frost Armor. Melee final blows while you have Frost Armor create a Stasis Crystal. Grim Harvest: while you have Frost Armor, your melee hits Slow targets. Defeating Slowed or Frozen targets while you have Frost Armor creates a storm that Slows and Freezes enemies. Glacial Harvest: while you have Frost Armor, targets are Frozen when you melee them, or they melee you. Shattering Frozen targets with your melee while you have Frost Armor launches Stasis projectiles that Freeze targets on impact.

They don’t work the same for each class, that you opened with that shows that you don’t understand how they are supposed to work or be different from each other yet still work between classes to provide benefits to each other. If hunters gained shards the way titans do a shatter dive hunter would always have full melee energy, but yep they all work the same because the collectible gives you melee energy. If it wasn’t for shards giving frost armour they would be useless to most titans because of how terrible the stasis melee is; it’s literally never used as a punch and most often used as a mid air lunge to make jumps I should have been short of making because of how horrible the targeting and unpredictability of actually hitting something you are trying to use it offensively will more often than not get you killed by lunging out of cover past your target or you launch past your target and over a cliff and die like Wile E Coyote… Also go see Elsie Bray she had new fragments to sell since the beginning of TFS that help your kit do what you want it to.
