Is El Patron's Lost Sword Overrated?

[ruisen2000]

I think it's definately overrated. It's actually not that useful in battle, it's only cool.
The drain voodoo skill is not very great, since voodoo enemies are often very easy for most people who are high level enough to obtain the sword. Except Jolly Roger, but before you can drain all his voodoo you would be dead already since he can knock any pirate out in 1-2 attacks.
Also the sweep boost is not very good, since sweep is weak already, +3 won't make it any stronger, if it was bladestorm or thrust boost it would be great. Also the patron sword should have at least 90 attack, since full moon special blunderbuss already have 88 attack, which is higher then the 84 attack the patron sword has, and seven seas has 80 attack, which is 4 less then patron, but 4 attack won't even make a little difference in damage, would it?
