They have decent reach, and the secondary attack works well. It's a good weapon in co-op, but not any more amazing than any other weapon you've become highly skilled with or can use a lot of stamina on. Also, no shield. When you get the mistlands atgeir, that's when it begins to come into its own right thanks to elemental damage type which you can abuse in rain and other wet conditions, not unlike the somewhat weaker but more defensive Frostner.
