I think all is them had parts I enjoyed, even WoD (challenge modes, PvP, raids).
If I had to rank them I’d say:
Legion
MoP
Wrath
BFA
SL
TBC
Cata
WoD
DF hasn’t been out long enough to tank but I’ve been really enjoying it.
I’m a sucker for class specific content and Legion delivered more than the rest of the game combined.
Between the banana peel and Ray Comfort.
I should be grateful I’ve never heard of Ray Comfort, then.
Wrath - Best storyline, plus Wintergrasp
MoP - Best class balance
Cata - My favorite dungeons and raids, and great guild experience
TBC - Loved the Ethereals!
DF - So far, so good
WoD - Good replayability
Legion - Only saved by the last patch
BfA - Everything just felt meh
SL - The only expac I’ll never level an alt through. No redeeming qualities imo.
Lol u like cata more than mop? Sry u lose this round of the game
