Nope:
In Legion I never complained. Thought it was one of the if not the best expansion ever. I had a bad feelig about BfA, and that mostly turned out correct, but I'm still having fun in guild with Raids and M+ etc.
I still feel the same about Legion now as back then.
WoD was the worst expasion ever.
I liked MoP, still do.
I wasn't to keen on Cata, that hasn't changed. Feels like with the old zones, WoW as a game was also changed forever. Less depth, more streamline.
WotLK was my first expansion, so ofc it felt epic. In hindsight it was a probably a good expansion, but not remarkable, but it will always b special to me.
I never played TBC, but it feels like it was a good expansion.
I played vanilla but not on retail. I like it, and I will play Classic, but I wouldn't glorify all aspects.
