Island expeditions
Artifact power
Warfronts
These were the themes that were in the advertisement of BfA.
Artifact power doesn't even fucking matter. I don't get why it's so praised like "oh our alts can level up their artifact power so quickly and get on par with our mains!". Even Preach thought to himself how the fuck could players have this mindset.
Question: if they removed artifact power, would you really, really notice the difference?
Island Expeditions: This one was a fail on their own already. 2 weeks into BfA and I couldn't even be bothered to do this shit.
Blizzard doesn't seem to comprehend that players like to do hard content, with good rewards or atleast content that powers up your character and makes it stronger. I couldn't give a rat's ass about cosmetic items if they aren't hidden behind hard to do content as a means to show off your power status ingame like a mount or a cool ass weapon or title. Not even going to begin on all the rewards are based upon RNG.
Warfronts: I gotta give it to Blizzard. I couldn't honestly believe if they could have ever designed a more boring gameplay system than LFR, but loh and behold, the most disinteractive piece of garbage this expansion offers so far.
Rest of the game is just rehashed content. WQs, M+.
Azerite gear giving the players a new system around gearing isn't something to be proud of either. I love how they removed raid sets because of minmaxing, and in the end Azerite gear gets simmed and minmaxed anyway.
