Gear inflation.
It removes content or makes it obsolete - sure it can also open new content for you, but if you are doing the content already you don't care about that anyways.
No sense of pride and acomplishment getting a titanforge, it's pure luck - nothing I personally did in game, outside of looting the item had any effect on it.
Non-forged items, are like bad azerite armour, it just feels bad to loot, unless you are super undergeared.
The thing that pisses me off the most, is the fact that there is no player choice involved in forges, a monkey could play this game and get the highest ilvl - if all you do is wq and pet battles, then surely 340 and the plethora of free 370's should be more than fine?
Don't know why its necessary to have the amount of ilvl equity we have in game at the moment, make epics feel epic again, and let me enjoy the gearing process for longer than 2 days. It's like d3, where you log in, rush max lvl and bing bong 15 h played later you're fully decked, and then people go complain that there is nothing to do.
