As for the problems frequently talked about the next patch coming next Tuesday will address many of them, including but not limited to:
Azerite traits
Azerite gear availability
Class tuning
Professions
I don’t think it effectively addresses any of them because most of the 8.1 content is a nod to or band-aid fix. Blizzard will prob have something new going into 8.2.5. either to get us to forget the Azerite garbage that is current or an adjustment in the form of making it more like the Legion artifact weapon but that’s all the tuning you’re likely to see this expansion unless they take class design and balance more seriously.
Either way, Locking a talent or trait behind loot and not the actual class talent tree just begs for the community to get riled up.
So to answer your question, no I don’t think Blizzard is trying to kill their own IP, but leaving the classes in a crap state and expecting people to continue to pay to play is a bit much.
I’ve played WoW since vanilla, I quit during WOD as it just plain sucked and I feel BFA is worse. I never understood why a company like Blizzard would release an expansion with classes not done. If our abilities are an interface to our characters then our characters are the interface with the world, story, and everything else included in the expansion. Even if you had to release early to satisfy investors, then at least make fixing the classes a priority.
Not just a few but all of the classes need some attention, some are too strong, some too weak, some can’t/don’t PvP well, others can’t/don’t PVE well. I am not saying Legion didn’t have issues, but by this time we were well into the next patches (7.1-7.1.5) in Legion and some of the artifact unlocks were alleviating this issue.
Patch 8.1 will not fix this and I am doubting 8.2 will address many of these issues.
It’s funny I can remember a time when the community could somewhat interact with the developers and quite a few folks in the community pushed for some changes to rogue class (PVE) in WOTLK that had they been left in place, would’ve killed the fun in that class for PVE content. Other classes not so much; the community really clashed on the warlock changes in that same expansion as Warlocks lost the ability to help themselves out of a jam in PvP situations because of the change in fear and not giving the class an offset mechanic to help escapes unless said warlock knows he/she’s gonna be ganked or targeted. To me, that expansion’s big issue was the number and how often the classes were changed/tweaked after the expansion launched and letting DK’s and Pally’s ride too long on being way way way over powered but even with a few missed/false steps at least Blizzard was trying and making changes to the classes.
We have an expansion focused on war and I am assuming large scale PvP since we now have War mode but there are classes I would NEVER solo quest with warmode on.
