Claws aren’t that hard to fight, just stop panic-parrying. They’re harder to use effectively than to fight against, especially with the shit damage. Also, claws are a good counter to polearms, try it out. Wait, you’ll get rekt and come back and whine more. Again, it’s true that some weapons need tweaking, but it’s not as if certain weapons are so OP they beat anyone. Halberd is a great weapon for team fights and 1v2s l, but a good player can also use a Kanabo to VERY effectively counter him. Or claws, or blunderbuss, or any viking weapon, or dory, blah blah blah. The skill determines the true potential of a weapon. Sure, the halberd and claws are two that really stick out as high-skill high-reward weapons, but are they really OP? No.
Claws are a good counter to polearm because it glitchy to parry against especially those that uses rolls correctly and the fact ninjs can run toward the sides and hit through parrys. You can fight against it but it still a glitchy mess that need toning down at the very least. And Kanabo? even if it has good attacks its very readable.
