I think because of Kara/Heroics the average player is seeing a lot more useless purple than they used to but the number of enchants that require void crystals are just as expensive and limited as the ones that needed nexus crystals used to be. I think if they had done the sensible thing and made Kara in the same mostly blue some purple system as the old 20 mans things would have been a bit different.

Someone asked about reselling earlier and I think my biggest tip there is to watch the low level blue market. You will often get just as much for a level 29 item as you would for 69 and the ah deposit is almost nonexistent so you are free to relist until it sells (unlike buying a 70 blue which will eat up your profit quickly if it doesn't sell fast). This of course depends on the server being fairly established and lots of people twinking or just having the cash to buy their alts gear as they level. Do pay a little attention to the stats though, some are much better than others (though people are strangely blind to that sometimes when they see blue or purple). Aim for the sub 50 market, any later than that and people start thinking "I might as well wait for Outlands".

Edit: Just a comment on:
"Kind of curious because you rarely see people selling enchants with their mats. I'd assume it would be more convienent and you'd get more business. Hoping it doesn't have more Cons then Pros."

It isn't worth it outside of special occasions (s3 release I stood around yelling about stamina and res enchants including mats and sold a fair amount). People will harass you for 15 minutes over your quoted prices even if they are lower than the price of the same mats in the auction house. Honestly both sides seem to prefer skipping the haggling, they would rather get overcharged by a faceless auction alt than feel unsure about a deal with a pixel to pixel person.
