While I do not consider myself a Wrath baby, because I started mid-TBC. That said, I agree, Classic will be for those that loved the hell out of it. The many that started to the game after Vanilla will simply not want to endure the far slower pace and nonsense that got refined over time. This also said, I don't really care for where Blizzard has chosen to go with this game, but I do understand and chose to adapt to what Blizzard has done, but I still play the game the way I first started to play the game, which is not really all that different from how many tend to approach Classic or Vanilla WoW. To me WoW, is always going to be a journey type of mentality. I always explore the zones and content before ever starting to quest. I like to get the full immersion and feel of the landscape first and foremost. I have leveled so many characters since I first started playing this game and I never start playing any of those characters in the same manner or start in the starting zones for that particular race. I rotate around so I can recapture the feel of the various places I have not visited for many moons.
Many seem to complain that the game at it most basic levels has changed over time. When in fact it is the person that has chosen to change the way they choose to play the game over time. I still do the same things I always have done, no matter what changes Blizzard has chosen to make. I still see this game from expansion to expansion as a journey that will unfolded over the course of the time I spend in the content. I am a purist when it comes to new content and always approach that content in the same manner as I first had done with my warlock some 11 plus years ago. People chose on their own to change how and what they do in this game.
I continue to play like I did from the first moment I logged in and created my warlock. I still interact with people that are worth the time to interact with. That too has changed over time, now there are far more jerks than people that literally want to give their shirts off their own backs. I still go out of my way, even if I am in the middle of doing something to go help another player that is asking for help or assistance. The game has changed over time, the way I approach and chose to play the game has never changed for me. So the people whining about everything under the sun that made Vanilla great or more social interaction and sense of community are the people who changed over time. Blizzard in many ways was forced into rolling with those changes. In my opinion, Blizzard went to far and should have let the dust settle a bit, especially during and after Wrath to see where the player base itself was going to go before forcing the player base to go in certain directions.
This current expansion is like taking the approach of throwing everything and the kitchen sink at the base without really making many work for just about much of anything. I get the game has gone far more casual over time, but people still need to be given some semblance and incentive to want to go into content. Not continue to dangle carrots in their faces so they go into the content. It is nice to get an occasional mount or pet, but this expansion see like if you do this you simply get a prize for bothering to participate in this content.
There is nothing, pets, mounts, gear, or whatever that Blizzard to throw in my face to get me to do an expedition at any level. I simply think those expeditions are a complete waste of my time that I could be spending doing something else far more engaging. Expeditions are like the Darkmoon Fair, but then that is not really fair to the DM Fair at all, but the same level of mentality actually applies to a lesser extent. Do this and you simply get a carrot, whether you wanted the carrot or not does not matter, you receive the carrot just the same.
