Let's put it this way why titanforging wasn't good: People would be getting good pieces out of even heroic, and many of them wouldn't be trying hard, titanforging would mean you wouldn't need to do stuff on Mythic to get Mythic gear ilvl basically. Not that the RNG is always so good to you but if you do heroic too much and not a single Mythic and get titanforged, it's equivalent to mythic gear. And + sockets RNG. As if it's not enough, you could be lucky on having a socket with titanforge piece.
Mythic raiders feel like their purpose of doing mythic is just progression itself, nothing more. Gear ain't even a good thing this xpac, there's no tokens from tier sets, etc.
Basically it's screaming you can get ilvl 440+ doing everything but mythic. Needed to stop. I won't miss titanforging, players that don't want to do stuff like raid and mythic should be punished on the gear. It feels more unique, instead of showing your "look at me, i don't even raid but got a piece that titanforged with a socket" and raiders will be like... "ugh, lucky you..." Titanforging was bad imo. That and sockets being random, kind of makes gear too much RNG based, and not difficulty based.
