I will be posting my personal tier list here. This is for funsie discussion feel free to post your own tiers
S Tier (God Tier can stand alone and be played forever) -
Vanilla WoW. It’s the only virtual world with unlimited replayability.
A - Tier (award worthy 9/10 expansions)
Legion - arguably the best story in an MMO expansion in the history of the genre, Class Halls, solid PvP balance, great raids/dungeon design!
The Burning Crusade - Built on what made vanilla great, difficult Heroic dungeons forced players to play better and use CC/interrupts. Goated PvP for the original Classic Trilogy.
Dragonflight/Mists Of Pandaria - Both these expansions were masterpieces for their respective generations. MoP was a bridge between Classic and modern and had amazing class fantasy, top tier raids, and content that respected your time. Dragonflight in many ways imo is MoP 2.0 being very well made all around in all categories especially when it comes to respecting the players time.
B Tier - (Not good nor bad 7/10 expacs)
Wrath - Easily the most overhyped expansion in the history of the genre replacing Planes of Power. Worst era of PvP considered by many competitive PvPers (until SoD released lul) good raids, terrible dungeons. The expansion was mostly carried by the hype of previous expansions. ICC and Ulduar carry what would otherwise be a C tier expac imo.
Cataclysm - LFR, Heroic raids, bringing back hard heroic dungeons again after wrath made heroic dungeons a laughing stock, considered a top contender for the best PvP of all time. Cons: destroyed the old world, still hasn’t been fixed 15 years later. Old world flying really made the world feel small for the first time.
C Tier mid expacs 5-6/10
Warlords - No content. Rehashed story. Turned Arena into an e sport hurting class fantasy in PvP. Scuffed player housing. Overall mediocre and cut short.
BfA - terrible itemization and a missed opportunity of making PvP war campaigns. Strong 4th war story overshadowed by weak forced Sylvanus story.
Poopie doodoo tier - Shadowlands. It was bad. Almost nothing redeemable besides mogs.
