I'm currently thinking about returning to WoW. I quitted in the summer of 2010 when ICC was the highest raid instance available, just a few week before some new instance was released (I think the new one was next to Sartharion?). I quitted because my girlfriend who also played lost the interest and after not playing for two weeks I didn't miss anything. I played quite casually in WotLK, did semi-random raids (10 and 25 people, although I had a fixed group for 10 man raids) but I liked it and raided with all of my characters (mage, priest, druid, paladin of which only my mage was a damage dealer).
Since then I didn't play multi player games except for Diablo 2 and Diablo 3 but quite often I found it dull and repetitive. Thinking back to WoW, I remember that I almost always had something to do, some goal I could work towards. I raided enthusiastically in Vanilla and BC and made a personal change in my gaming habit which made Wrath of the Casual quite appealing to me.
What do you think: Will a return to WoW in the current state make me happy? How much has the game changed during the last two expansions? I read an article just before MoP that described the new simplified talent system and although I was disappointed initially I began to like it after playing Diablo 3 and it's simplified talent system for some time. What else has changed? What do you miss when remembering the early years of WoW and what new additions do you like? Do you think one can return to WoW after 2,5 years?
I know this question is hard to answer but any opinion is appreciated!
