Wolver, Flourish, and Owlite lines are more practical for common use than some other equipment like Chroma or Jelly. Wolver is as "overpowered" as Gunslinger and SDemo line, except for Gunslinger starting at 3* and SDemo not having any status resistance until 5* while Wolver has some freeze resistance starting at 2*.

Brandish is only "overpowered" because the charge is too spammable. This and other sword charges could be "balanced" by placing a cooldown to prevent charge spamming or elongated the charge times, though the former is more likely to happen due to Three Rings being biased to swords to minimize due punishment.

Troika is only "underpowered" compared to Sealed lines, and mostly to its lack of projectiles. Projectiles from melee weapons are for Palins.

Calibur has the same problem as Troika, it lacks projectiles; which I question the necessity of for a melee weapon. If I pick up a stick and swing it at people, should it should pixies? Calibur is still usable, though its basic attack tends to do a little less than Brandish lines, but its charge is still gudd.

Angelic was apparently supposed to match with the Sealed lines, Valkyrie for DAvenger and Fallen for GFaust. You figure out what can make that happen.

Have a sandwich.

And some chips.

idk if you people see Skolver OP because "LD" but the Gear have their own purposes. i wouldnt bring a skolver for an elemental mission because T3 mission a hit with elemental damage wearing a piercing armor means LOTS of health lost. idk if a good player with a gear make you people think that gear is OP, isnt the same thing look a player with the same armor that dont have a lot of experiencie in game that a guy who played this game for a long time and can do whatever level he want with proto gear.

The game need less NERF, they need bring back the old monsters. even people with "OP" gear died before when the monsters were a real danger, not the joke they are now. hell even i think they nerfed the alpha wolver bite damage.

Calibur need a buff? idk if you really played with one or take you seriously but i even take down Seerus Tier 3 with a leviathan blade and i feel it more useful than any other weapon i could use agaisnt him. or have you ever read doctorspacebar medicine for boredoom thread? one of the achievements are to take down Vanaduke with leviathan and its pretty possible with it. leviathan - calibur line its the first sword i always tell to my friends to get its perfect to solo every level because the pushback and the sword damage charged. what i agreed that need a buff its the Iron Cold Vanquisher because its better to use a leviathan even with Max Damage leviathan still keep doing more damage that the ICV.
but as far they dont change the "360" charged attack of the leviathan im fine with it. that sword its really pretty helpful for me.

a sword without a "BOOM" charged like the Brandish line dont means its useless. Play more time with your calibur. the brandish line was really pretty bad back then. random explosions even for 5 stars. but i always have my glacius before the buff of Brandish, because i see was pretty quick to take down roarmulus with 3 hits from my glacius than 2 hits from my divine avenger. i never made that sword because the charge, i made it because i needed a quick sword elemental.

Cobalt like... ehh well that need a bit of improvement same with the Jelly line, i guess they have those bonuses on the Chroma line because they never expected to add damage trinket to the game. so what Chroma and those armors lines what need its "another kind" of Bonuses to make it different from other armors.

What the game need its MORE armor for specific player class. they have gunner set, bomber set (without one with shadow protection and piercing which its pretty bad), but they dont have their own shields. if i recall correctly they buffed the bombastic set because before it give low bomb damage, now it gives medium damage which its something.

i only give you +1 that they need to bring back old monsters and the "difficult" they were before. but your other points no. well maybe a +1 to the troika line but i cant say a lot of it because i never have one maybe i would craft my next weapon a sword from the troika line specifically the ice one.

On the other hand, the changes made on Skelly/Retrode melee are understandable, as latency made CQC with them a hell.

Nobody remembered the cutter line. They're so risky to use and yet they are so weak. Especially the Wild Hunting Blade.

As for enemies, I think wolvers should get their auto-aim back because even back then they were still sort of weak (except for Alphas who would just destroy your shield).
