Legion was really cool i loved the new class and story as well as the world events.
Lich King Bay Bay!
Wrath of the lick King added so much and improved on the games story in so many ways. The death knight class, lich King dungeon, new mounts, a New starting area and the 3rd lich King at the end of the expansion. This update brought my favorite villian and my favorite class in the game. Its better than some expansions(looking at you bfa. You dumpster fire.)
I wasn't really old enough to experience the entirety of BC or WOTLK (though I do remember part of my experience in WOTLK); however, I feel MoP was the best expansion out of what I was able to play in its entirety. This being said, I feel that late Cataclysm forward they strayed from what they intended the game to be. I am currently enjoying classic as I played a month of BFA to promptly quit. My love for this game tanked near the end of the ever-repetitive WOD and I have been rarely on since due to my newfound love of final fantasy.
You may ask yourself: Why in the gods' name did you pick MoP? The raids may not have been amazing. The content lacked and introduced our (now) RNG-RNG-RNG upon RNG overlords. Flex raiding was weird and not what we wanted. "They added kung-fu-pandas." Okay, I get it. The thing I loved about Mists was the class dynamics they had. I loved healing more than I ever have or will. This expansion highlighted all the classes and made me find more than a few I enjoy. These dynamics were later dismantled and taken like the talent tree of WOTLK that everyone is so fond of. Healing will never be the same for me. I don't even play some of those classes anymore, like priests (which I am now maining in Classic.)
Regardless, I look forward to (attempting) Shadowlands and hope it is all they claim they want it to be.
Legion definetly because it has best story ever I have ever seen and musics
Wrath of the Lich King because of the in-depth storylines (even minor ones for short dungeons), the quests, the environment and architecture, revisiting Naxxramas since late Vanilla, the color schematics that blended perfectly, the endless array of addons which included DBM, revisiting Northrend for the first time since Warcraft III, the music soundtrack, the publicity and media hype including cosplay, the introduction of Achievements, being able to go back to the sacking of Stratholme and reliving the original Warcraft III storyline which added nostalgia, and last but not least, finally closing the book on the Arthas Menethil/Lich King story. Not to mention WotLK also sold more copies than any other WoW expansion combined apart from Legion.
