PC on Long Sword please, and a few questions

Gold - Barbed Long Sword of Defense
Slashing Dmg: 15-22 (req. 11 Swordsmanship)
Damage +13% (vs. hexed foes)
Lengthens Bleeding duration on foes by 33%
Armor +5

I'm still trying to figure out the base mods pricing list....

Questions...
1.) Are the base mods the only thing that apply? (In other words is there no value attributed to the fact that it is a max dmg sword, in which case the above item would be worth 4K according to the list right?)

2.) Is there a limit to the number of mods that can be placed on an item, and can they be replaced?

3.) What the hell is the point of having blue and purple items... they seem to be completly useless.

Anyway.... thanks for the help!!!

according to derrtyboy69 worth about - 2-3K if Im luck.

1: Its worth 2-3k, if you can ever find a buyer. Only the bas mods apply, unless the mods are popular and perfect (10% furiours, 30 hp, vamp)

2: You can have one hilt and one pommel on a sword at a time, and can be replaced at will.

3: If there was no blue or purple there would be no high end items, and then no trading market. Also, newbies need to use something.
