That interview was a lot of fluff, and only one thing really caught my eye:
Planes of Power, anyone? This one of the major things players didn't like about later EQ expansions, even though I see the logic behind it and understand it was for the players' own good. Of course, one of the largest problems with this was spawn competition. Even on a non-PvP server, EQ guilds could selectively screw other players by camping select chokepoints, notably Rallos Zek, that takes practice to be able to pull off for the up-and-coming guild. At least in WoW, hopefully everything will be instanced so there won't be that one dickhole guild that decides to cockblock everyone else.
Only the exceptions can be exceptional.
