Didn't the latest player poll mention that people liked the current levelling speed (power-levelling aside)?
Don't we ALWAYS see a billion infinity+ threads complaining that levelling is too fast/idiots who think that you actually can get to level 50 in a week or some other imaginary time without PLing?
Wasn't the interview aimed at people who DON'T play the game?

I am very sure things will stay as they are
