I think it still shows wrong information on the website.
This is what it shows for my warspear:
Tempered War Spear
weight 1.5
difficulty 10
spd rtng 98
weapon length 150
swing damage 22, blunt
thrust damage 31, pierce
According to a clanmate, that's the same damage and 1 speed faster compared with his MW warspear.
Might still be off for other weapons too.
