Actually one final note. The 9.2 zone. You need to do daily quests there and grinds for a currency. You then need to buy upgrades. Some upgrades research in a day, some take a week. Flying in that zone right now with the PTR is locked behind about a month of a grind assuming you have the currency and keep chaining the upgrades the second research on one finishes. Part of these upgrades? Understanding the language of the NPCs in that zone. Yeah, they timegated dialogue.
You'll spend over a month doing daily quests in a new zone that will get old very quick, all so the second the next expansion comes out it's literally useless. At least Eureka and Bozja have some level of use, or replayability to them. Not this. We did the same thing in Nazjatar back when Shadowbringers released (they dropped the same day) in 8.2 (development cycle coming into perspective yet? Btw, BFA ended with 8.3 then was a what, 8 months wait until we could prepare for Shadowlands and play prepatch?) in that time XIV went through ALL of Shadowbringers and dropped Endwalker. WoW managed two content patches and an expansion that brought very little to the game in the time Square managed five major content patches and an expansion launch.
Other significant gripes: Beta testing. They invite some to try out the beta at random for the new expansion. We always notice flaws in the systems (oh yeah, they LOVE borrowed power systems now that are quintessential in current expansion, useless in next, full of bad features people will hate. In Shadowlands it was picking one of four covenants that all gave you spells. They were told in beta they needed to allow free swapping. They ignored it. Then it had to be a selling point feature of 9.1.5) and point them out on the forums. Blizzard ignores it willingly and ships it in a bad state. Then spends half the expansion fixing things people told them from beta were bad ideas and giving them the exact solutions they inevitably implement. Though they'll spend a good year defending the system saying it's actually really good if you just give it a chance.
Really does feel like the developers do not play their own game with regards to WoW. We did the same thing in Legion when we told them "Hey these legendary items are way too powerful to not be targeted." Blizzard relented at the literal final patch of Legion and added a way for us to pick the legendary we wanted if we didn't get it already. Oh yeah, you didn't work toward them. They were random drops and if you got one, you had about a 50/50 chance it was a trash one with some of them being mandatory for classes to feel right. Then in the next expansion they have a successor to that system called Azerite Armor. It gave passives. We told them in beta "Hey, you need a way for people to pick pieces they actually need instead of being pure luck." They deleted the BFA beta forum due to the criticisms being too many then dragged their feet until 8.1 to add a way for us to target pieces in.
