Balance Ideas
Status Flourishes and Cutter - Status Chance Increased.
These weapons deal their status way too rarely, why would I not use their more damaging counterparts if they can't status very often.

Hunting Blade and Wild Hunting Blade - Damage changed to piercing.
Nowadays us players can obtain Damage Level Maximum very easily. So this damage bonus versus Beasts on WHB isn't very useful at all. If you give it piercing damage however, it could be a nice and fun weapon.

Troika - Damage Increased on both Basics and Charge. Troika line can now do Stun on basics.
For being the heaviest and slowest sword, for some reason it does not have the highest damage per hit in the game. This makes no sense.

Catalyzer Lines - Radius Increase on charge bullet. Tagged Explosions will now detonate tags caught in the explosion.
One of the biggest problems with Catalyzer Lines is being unable to consistently detonate tags. Allowing for tagged explosions to trigger each other will allow for chain reactions, making it much easier to detonate when combined with the enlarged radius.

Tortofist - Remove hit limit on lodged shards. Maybe add Shock Status to stay true to the Tortos attack?
I don't understand why the hit limit exists. We have weapons like Blitz Needle and Dark Retribution that can hit multiple times in a single attack, so why do we need one here? The hit limit will removal will allow Tortofist to rack up a lot more DPS on its charge. If you add shock, that'll also help with preventing the insane knockback, allowing it to hit a single target many times.
