Nice addition. But I'll say it'll get boring soon.
Vanilla wow (assuming they don't change it) is mostly nostalgic. The game play itself is tedious and grueling.
On top of my head:
No flying.
No lfr/lfg
No instant que
Hunters still uses quiver and have to have arrows to shoot
Long travel time, mostly walking
40 men raid. We barely have 20 for mythic these days.
No multispec, you have to respec back to capital
Shit and one dimensional loot
Unless they bring the new world into the server it really is a nostalgic novelty.
To be honest the wow classic private servers functions well with regards to all those issues. Finding people for groups / raids won't be an issue unless blizzard makes way too many servers and splits the player base across them. I've lvled a character to 60 on a private server and had no trouble at any time to find groups for content. I never raided but had a friend who did and he had no issues finding a guild capable of finding 40 people for raiding MC and BWL (only 2 released at that time).
Stuff like instant queue, flying and lfr/lfg removes so much of the epicness feel from the game, to the point where you don't meet anyone in the world, except for 4 random dudes you barely talk to while blazing through dungeons in 5 pulls. As duffer says the server community feel is completely gone from WoW nowadays, which is a massive change for the worse, and honestly one of the things I miss most from vanilla.
As Tommy also says the loot is way more shit and one dimensional now. It really feels completely irrelevant and boring to get upgrades these days, especially with weapons being the same throughout the expansion. Warforged/titanforged is also shit and boring.
Stat priorities nowadays are extremely onedimensional compared to how they have been, very few classes have crit/haste caps, etc. Mostly you just go for one main secondary with the rest of them being subpar. I remember playing a shadow priest where I had to figure out how to hit hit cap, certain haste threshhold for my mind flay ticks, etc. Now you just go for as much haste as possible, without thinking about anything else.
I like both game modes, Legion is fantastic and has been the best expansion ever with regards to content as a whole, but I will definitely also try classic out and I hope they keep it as authentic as possible or else it will fail.
Ah.. Vanilla. I spent hours farming with my ice mage for cloths, and when I finally get my vanilla fast mount (cough... a skeletal horse) with 100% run speed I'm so happy.
There's no itemization back then, it's just an X Int / X Spirit or X Int / Y Stam, and that's all. Most of the stats we know today aren't there, namely (Mastery, Crit, Haste, Vers). Back then there's only INT/STAM/SPI/STR/AGI. There's alot of fun for us back then, I remember my guildies walk me to Burning Steppes, walking dangerously through half the continent, it was exciting back then, but very tedious, I'm not sure I'd want to go there again.
I'm not sure how Vanilla is Vanilla, but it'll probably be a mix of some new content brought into Vanilla. Vanilla isn't technically harder, just more tedious it feels harder. Most of the dungeons are difficult because back then we don't haev the tools to properly run it.
I remember leading a 5 man group in Scarlett MOnastery where i have to yell "Sap left, Sheep Right, Trap Second Left, Kill Center", was it fun? It was back then, WOW is head and shoulders above the curve, but going back there again.... /shudder....
Simply not true. Crit, spell crit, hit (hate it or love it), dodge, block, +def, mp5, +dmg/healing all excisted back then, arguably more different types than we have today (and that is not listing all of them).
In the end it is all about the nostalgic experience and the ride down memory lane for most people, and judging from the activity on the private servers it will definitively have some success, but only if they don't change it to some sort of shit modern vanilla hybrid and they don't make way too many realms. Rather have them very full than almost empty.
The whole experience of a dungeon actually being challenging rather than just being a massive aoe rush as most non-high level mythic plus dungeons is now is definately a plus.
I'm looking forward to trying it, was my first real introduction to playing computer games and have so many memories really growing up while playing this game. Feels like such a defining part of my childhood. Having LANs with friends leveling characters. My first flight from moonglade to teldrassil (started as a night elf druid), I was really mesmerized by how insanely massive the world was walking to elwynn forest to quest. I remember grinding to get my epic mount too in Tyrs Hand and it felt like such a big reward when I finally got it (compared to getting getting similar stuff now is just meh, not really any epic feeling in the world now).
