Enchanting- disenchant everything?

[Gladiator]

Should i disenchant every green and above item that i get that im not going to use myself (or give to a good friend)? Ore should i AH some/many of them? Currently ive just been disenchanting everything except what im going to wear o_O.

Blue BOE items keep/sell
Green BOE - d/e
Blue BOP - d/e (unless you are gonna use ofcourse)
Blues = shards
Greens = essences/dusts/(chance of a shard in some cases depending on the item)

Beyond that: it really depends on how much you can sell them for.
Weapons for example, are rarely worth disenchanting.

You have to know what you are going to get from a disenchant, and how much that's worth.

Basically
20- Strange Dust (Prime Zone is 18-20, because you get 5 or 6 usually)
21-30 Soul Dust (PZ 28-30)
31-40 Vision Dust (PZ 38-40)
41-50 Dream Dust (PZ 48-50)
50+ Illusion Dust
Of course essences and shards will get better with lvls too, but they aren't as reliable of an indicator as the dust.

If you can sell something for more than the market value of the enchanting supplies, then sell it. Even if you are trying to lvl enchanting, it would be more cost effective in this situation to just buy your supplies, and sell the item.
