Now that I've stopped laughing, let me say the following:
I can't believe you are comparing a weapon that drops in HoH (tier three pop zone) with a weapon that is quested using KUNARK drops.
I can solo the wurmslayer quest with my 54 druid. I can't even get FLAGGED TO ENTER halls of honor.
BUY the longblade of vitality??? Never even seen one for sale. I'm sure it would be 50k at least on my server.
The poster above does a good job of explaining why this comparison is faulty.
BTW, I have a wurmy on my 33 Pally. Usually use an argent protector, but like to pull out the wurmy and a shield when fighting casters. Does a darn good job at that level.
