The wilderness PVP removed: It was a good removal, good loving riddance of that horrid setting. I never stepped foot in the wilderness because of the threat of getting assraped ass soon as I hit level 30.
Grand exchange: That place is one awesome ass area. I cleared out all the junk in my bank and made tons of cash (in my numbers, atleast) and got a nice dragon longsword.
New graphics: I agree, I hate them.
