Why Can't you use Grips when using H2H?

:/

No one else realize/remember that there are Shadow-type enemies in Fei'Yin that can use only 1 h2h piece, leaving the other hand empty?

Players can do that too if they leave their main hand empty and equip a shield offhand. You can't use H2H WS if you do this however.
