I would love to be excited by that patch, but honestly the more I see what's coming the less I am. What we are going to have is:
Nothing but an Argus like Area with a buch of quests and mobs to annihilate, we will crush trough everyting within a very low amount of time and the rest of the quests will be time gated because it's the only way Blizzard found to makes shit takes some times in this game. And ofc we will have to comeback to theses area to farm some stupid AP quests endlessly, just like we a re doing since Legion
New Neck Spells/Procs that are nothing but interesting. I tried the upcoming bosses for the next raid on the PTR and with I put my hands on theses new traits and honestly there is nothing interesting or funny about them. The class specific ones are basicaly a proc of your major cooldown or a already existing PVP talent. The rests (common to everybody) are just a bunch of procs or on use burst cooldown but they don't have any identity and they are good/bad depending on how your spec is working. They feels very blend and the lack of Identity to the class/spec just doesn't feels good at all, it's like I'm using a trinket or something but not a spell.
There is actually way more procs that I was expecting in the new neck traits and it's actually anoying af, especially when considering that BFA is already completely overwhelmed by stats, damage and defensives procs. It's a nightmare to deal with all theses procs when you care about your character beacuse it feels like I loosed control of my character.
And shit that's already it, there is also a new dungeon/raid but that's expected with every patch and it's probably going to be good as usual.
TLDR: If you didn't liked BFA, you are not going to like 8.2. If you liked BFA, it's just more of it.
