Green vs Blue prices
 

These are going to seem like awfully basic questions, I am afraid but here goes.

Should blue weapons be enhanced? Is there a substantial enough difference in selling price in the end between a blue and a green that is enhanced?

Can a blue be changed into a green?

Someone gave me several blues and I do not want to waste my time enhancing if they sell a lot lower than a green.

TIA.

As far as I remember +9 blues sell higher than greens,
Blues cannot become greens.

Blues are more expensive, cause:

A) They're harder to find.
B) Dropped by high level mobs.

This is based on Epith but a non-enhanced blue weapon will go from 5~7g. Once it is +9 it will go anywhere from 15~25g+ (especially for Axes and Wands).

WOW thats expensive, i buy my +9 blues for like 9-10g and resell for 12-15.

As far as it goes yes blues are alot better and worth it to enhance.
They have better atk rate, better crit then most weapons, and higher dmg.

Yeah, they are expensive. I envy the prices in Teva... T__T

And don't forget better aim as well.
