It is weird to see how people talk about Vanilla WoW and seem to have forgotten (if they played) just how tedious it could be and the large barriers to entry for end game activities (i.e. Raiding). I mean I remember it because it was like the second MMO I ever played in a serious way. I put soooo many hours into, but the thing is the vast majority of those hours I don't think really were much fun in hindsight.
1. Waiting, soooo much waiting around, was unreal, people just have no idea how much standing around waiting with your thumb in your ass you did. And don't try to tell me I was in a shit guild or something, you waiting for everything it was why shit took so long lol. I mean people go on about how long it took to level (world first was 10 days btw lol) but a lot of that was tedious running and more waiting.
2. Raiding.... gah. MC was so boring after you had done it 20 times, soooo boring. BWL was tedious at best, AQ (this is where my raiding ended in Vanilla) was just a shit place in general, just terrible. (Let us not forget the total lameness of ZG and AQ20... shudder, wiping for hours on shit tuned bosses to get some crappy blue.. fun times lol). I find it super funny a lot of people in the thread keep arguing about raiding in Vanilla, it was pretty terrible.
3. Lack of things to do, there was very little to do at level cap if you didn't raid. PvP was a uber chore and not really worth messing with until BC. Dungeons was a about it but you had what 4 or 5 max level dungeons to do? Two of them being 10 man (originally 15)!
I dunno there are so many negatives I just can't see going back being much fun in the long run. Sure I will try it just cuz why the hell not and maybe I will be wrong. Maybe it will be super fun, more fun that I could imagine but I doubt it. Going back to play old ass MMOs always ends in quickly becoming bored and those private WoW servers are a joke.
I do think folks need to remember that this is very likely a marketing thing mostly (and probably nostalgia from the dev team as well) for the huge, huge WoW 15 year anniversary that is next year.
I mean we just don't have many examples of a game with WoWs lifespan, it has evolved and expanded and morphed so much over the last 14 years, it is amazing to me it is still around (I am amazed I still play it!). So Blizzard has something to be proud of with WoW and I can see why they would want to celebrate with Classic, but make no mistake that is what it is, a present from the past, not the future for WoW.
