Just want to say that BfA gearing system was a fail even from its beta. Pretty much every "influencer" (uhh this word gives me chills) streamer, as well as us with lower voice, provided tons and tons of feedback why Azerite system was nice on paper but it would never work in real application.
They ignored us. System failed.
To scrap it from utter failure early on in expansion they added additional outer ring. Which then just brought to light already lingering problem of badly designed and poorly balanced traits.
This brought into the light few classes that were beforehand perform inline, but again, high on the meters by boosting them further and pushing them into "meta".
As Azerite Gear system was dead in the water they decided to add another layer of progression, essences.
Again, interesting designs behind them, but the way that they interacted with the classes was not balanced (nor it can be tbh) which again boosted power for some specs even further.
Finally, nail in the gearing coffin for this expansion was corruption system and its ability to buy SPECIFIC corruption that you need.
Ability to buy specific corruption further more highlighted already "broken" classes that benefit from extreme amount of stats, previously unreachable (or hardly reachable) by normal gameplay.
Looking at it, you have 3 different "borrowed power" systems on top of each other, noting that this was never seen before previously in a expansion, and thats NOT counting in Trinkets, which are story on its own. Soo.. what did you (we) expect in end-expansion point with gearing system that was doomed to failed even before its implementation, but it was band-aided few times with even more borrowed power? Some balance maybe?
Yeeea, tell that to Bear druids and Blood DKs with 6TD stacks too. Not just burst classes.
Im playing feral with 3TD stacks, simply just by respecin into bear, without any gear changes, my TD procs wipe the floor in AOE and do spike damage that i cant even get close to with feral. I know its not best example, but its example of how broken current systems are.
Gearing system was bad from the start, with so much "borrowed power" in place its natural that the game will be "broken" in a way it is now.
Is it ok? OFC not. But i also dont see the reason to rework core of some classes that perform exceptionally well in end-expansion point with several "borrowed power" broken systems on top of it. I do, however, think that burst classes need a bit of rebalancing in their damage dealing windows.
I can just hope that blizz learned its lesion and same thing wont repeat in upcoming expansions.
