Re: leveling - Blizz's philosophy is that they want the amount of time played it takes players to get from 1 to max level to always remain the same.
So for ever new expac that comes out, leveling will continue to get faster and faster as the EXP tables are re-adjusted.
Maybe they won't follow this pattern forever (by level 100 players might be flying through levels stupid-fast) but that is their 1-84 tuning philosophy for now, at least. 1-60 in Vanilla takes the same amount of hours played as 1-85 in Cata.
