C'mon, I think everyone is getting tired of these complains about classes, weapons etc...
If you think about it, the spear has one of the worst triangle attacks in the game, it's slower than the hammer, and it doesn't allow crazy multiple air combos like the sword.
It usually does pretty little damage, and dodging is fairly easy it does track you down, but only for a set period of time, so it's all about time.
In the beta, swords had priority over hammers. I guess they responded by having hammers have a priority over EVERY weapon. The way I see it is:
Spears should be the fastest but weakest weapon. They'll have priority but do minimal damage.
Swords be slower than spears but faster than hammers. They'll do moderate damage. More than the spears but less than the hammers.
Hammers should be slower than both swords and spears but do a great deal of damage. Much more than spears and more than swords.
