Honestly, not sure if I'm going to play Classic or not. I simply do not have the time these days like I did in the past...
That being, said, I really do miss the simpler times. I remember, when I first bought WOW, reading the lore behind every class and the roles they could fill. I decided I wanted to play a Spellcaster then chose my class based on the Lore behind each one. My first 60 was Mage.
Today, while I understand the need for diverse gameplay, I often find myself at odds between class design and lore. In some ways, I do miss the old 1-2 button specs of Classic because deciding on a main was all about aesthetics.
