From the guy that brought you the BFA Positivity Thread, the moment you've all been waiting for! The motto remains, genuine positivity only, if you want backhanded sarcasm, you've got good company already.
First up, enhanced half-cutscenes.
I break down cutscenes in-game into 3 main categories: High-res cinematics, cutscenes using the in-game artstyle, and in-game model half-cutscenes. For example, here's a half-cutscene from just last expansion:

Now compare/contrast that to our most recent half-cutscene featuring Sylvanas. Note the incredibly detailed facial rigging they've added to lipsync and do subtle facial expressions comparable to a full cutscene. It looks much better. Every emotion is conveyed as intended, an undeniable step up from Baine's lips going "BLAB!" and the subtitles saying "BANSHEE!" I hope this is the norm going forward. Close ups without lipsync just look bad.
Next, player customization. In absence of allied races this expansion, Blizzard focused their efforts on enhancing older ones and underappreciated allied races. New jewelry and finally slanted eyes for Nightborne players? Consider it done! Scars? Tattoos? Scars and tattoos? Whatever you want! High Elves? Sandfury Trolls? Wildhammer Dwarves? Done, done, done! Even when it doesn't make much sense for a barber to be capable of doing it. Snip snip!
Lastly, leveling zones once again. We have a world on clouds where you're followed by a little owlet who will doot his little flute on command, picking them out like it's the Adopt-a-Murloc micro-holiday event. We have Ardenweald, which is like if everything I loved about the Emerald Dream, Teldrassil, and Suramar fused, to the newest Zereth Mortis, we've got some prime zones that I just like being in. Take a break from the grind, turn the music on, and just wander the forests living with movement beyond any prior zone, and you notice the otherworldly weather effects kick in as a shower of twinkling stars cascades down instead of rain. Incredible.
That should get things started!
