As I discussed in an earlier thread, almost every single weapon line has an unbalanced weapon along with a good one. Here are the good weapons in a some lines, along with their unbalanced counterpart. The better weapons are on the left, and the unbalanced ones are on the right.
Leviathan- : Cold Iron Vanquisher
Brandish- : Cautery sword
Dread Venom Striker- : Wild Hunting blade
Final Flourish- : Fearless Rigadoon/Furious Flamberge
Plague Needle/Blitz Needle- : Volcanic Pepperbox
Biohazard- : Neutralizer
Callahan : Iron Slug
Polaris : Supernova
Nitronome : Big Angry Bomb, Irontech Destroyer, Heavy Deconstructor
N/A : Deadly Dark Matter Bomb, Shocking Salt Bomb, Deadly Crystal Bomb, Deadly Shard Bomb, Deadly Splinter Bomb, Scintillating Sun Shards
18 unbalanced weapons right there. And these are just the WEAPONS, mind you. There are many more unbalanced pieces of armor and shields.
Do you think every item listed is unbalanced and needs a buff desperately? Do you think other weapons need to become more balanced?
Yes, I know that there are those on the opposite side of the spectrum that need to be balanced (Skolver, Polaris, FF) but the discussion is about unbalanced weapons that need a buff, not a nerf.
Look at the attack cancellation on DVS. Then look at the attack cancellation on WHB.
One of these weapons will get you killed if you try to use the charge on gremlins, and one will not.
Oh, and also, Winmillion.
