I did the worst yesterday, here’s the best today!
Thal’kiel
Not just ol’ Skelly here, but all the talking weapons we got over Legion have buckets of personality, and I have hopes (slim as they are) that they’re allowed to be chatty when transmogged to in Battle for Azeroth too, even if it’s just their generic battle phrases (like when you use Call Dreadstalkers, Jack Skellington goes “RELEASE THE HOUNDS!”).
Warlocks
Warlocks get the best stuff.
Raiding
Every raid had its standout (in my opinion!) boss. Il’gynoth, Star Augur, Odyn, Maiden of Vigilance, Imonar. The fact we had a decent number of raids compared to Warlords was another triumph, and while I’m a tad bored of fel green, the general aesthetic of each raid this expansion was very strong thematically.
I’ll never get bored of Old God purple though. Just saying.
The Mage Tower
Those challenges were amazingly fun, at least for warlocks. The twins were frustrating without Sacrolash’s Dark Strike, but easy enough after that. The demon worm and his master was a challenging ask, making such an interrupt-heavy fight for a spec that ordinarily has no interrupt! Demonology had Sigryn and her cronies, which was a mechanically demanding fight but by far the most fun of the three.
Also no spec had Agatha, because fuck Agatha.

*hiss*
Cinematics
The cinematics were fantastic this time around, and I am confident they will only get better going forward.
But still, Ysera… *sob*
World Quests
I know, they’re repetitive, grindy, and frustrating for people who just can’t leave a single quest undone, they’re still an amazingly solid addition to the game, and mean that rather than be holed up in our garrisons like we were in Warlords, we’re still, even at this late stage of the expansion, flying around the world actually DOING stuff. Long may they continue.
Trilliax
Filthy, filthy, FILTHY!
Void Elves
Practically topless. Rippling abs! Solid pectorals! And that’s just the girls!
