As someone who has played WoW when it came out for about a week or so: Yes it was.
I played WoW from launch up until Lich King. You’re week of wow is pointless and irrelevant to me.
It was never a bad game. Any QoL feature that any modern mmo or even online co-op game has probably owes its life to that game.
Few mmos then or now ever matched the scale or expanse of that game. FFXIV’s world can’t even breathe without having to be chopped into loading screens. Wow’s world feels absolutely seemless.
You can complain about quest design, but that’s any MMO and really ignores that end of zone quests, dungeons, or quests lines like Onxiya(whatever that dragon was) felt epic and more rewarding then most single player games. And more team oriented then most online games
Classes felt unique with talent tress offering some actual personality. Shadow Priests was a terror in PVP.
The world events and constants add ons that game has drawf any gass today. Adding battlegrounds I remember was an actual huge deal. I logged in and it felt like the entire world population was there to join up.
Yeah, WoW was in no way a bad game. You want a bad mmo. Play Guild Wars 2.
