There have been a lot of people talking about this, but I hope you allow one more person’s thoughts about Classic vs. Retail.
Classic has many differences between retail, some bad - simple rotation, game-breaking buffs, wildly imbalanced classes at the high end - but I wanted to talk about the one thing that Classic does right, and I mean really right:
In classic, you have a full game with some extra max-level content. The whole game feels integrated, all the way from level 1 to level 60. You can grind for rep, build profession skill, even get some high end gear before you even hit max level. There are a number of challenges you can face if you want, all of which are rewarded appropriately for the risk.
In retail, you have level 120… and you have the time-sink before you get there. The entire game prior to max level has no impact upon your play at 120. Moreover, there is only one real difficulty level below 120: super-easy.
Can retail please get a leveling experience that is more than just a day-long trudge to 120?
