Gear doesn't feel rewarding anymore, it's disconnected from progression because it can be attained anywhere. Titanforged muddies the water and means you can get mythic gear from any source now. Warforged was fine as a little bonus because it was just a small ilvl increase that didn't spill to the next level of gear, but now a quest piece can randomly be better than a mythic dungeon piece.
Blizzard think all this diablo random gear thing is good because it's a surprising and exciting when you get a random good upgrade. No, it's just frustrating when you're unlucky and relief when you finally get something, especially with legendaries. They don't let you work towards anything, it's all luck.
Remember when items were items? Oh you've got an item from Kara? Nice! Oh you've got tier! Great! You've got a legion item? What's the complex tag under it? I no longer feel any sense of joy when getting an item because it's all about the tag and the item isn't important. I miss shoulders being known because of the item istelf, not the tag. When there were only 1, maybe 2 versions of an item. (if things went back to a simple Normal Mode - Heroic mode raiding structure)
I know this is a whinge thread. It's not a positive thread but I don't think I'm crying for the sake of it. If nothing is ever said about bad things then nothing changes.
