On the PVE server, i think this isn't so bad change. That will help beginners to get gear more easily (lvl 11-19 range is priced 60s or more, but level 20-29 range most blues are almost given away or at mere dozen of coppers).
I still have a lvl 25 toon that i used to sometimes run epic mode, that change doesnt prevent me to continue doing so. It will still be as fun. Of course, i will lose a few silvers benefits from blue sales that i could make previously but i will be more than happy with that situation where beginners can have decent gear at decent price.
It was by far more frustrating to post items at trader for few silvers to see everytime that it was instantly purchased in bulk by other players who reposted them 10 times the price...
