Pop at launch was 1,3 milion plus A LOT on queues or out of servers trying to connect.
See, this is why people like you are being called out for being whiny dumbfucks. You do realize that sitting in queue requires you to have the game active and running, meaning they would still get tracked by steam-stats as having the game open. So those 400k people you're trying to conjure out of thin air to make your weak argument stick, they don't actually exist. If 1.3million people played the game back then, and 400k of those were sitting in queue, that means 900k were actively playing. Now you say there are almost no queues anymore, with a peak of 900k. So how many of those people are actively playing? Would that maybe close to the same amount, as it was on release? Say it ain't so. The only thing that is true, is that a lot of people quit. And a lot of people started. I really don't see how that is in any way a problem.
There's certainly an issue with bots, but its less severe than you make it out to be. Of course most of them will be found during the early stages, as they're basically just farming materials and collectibles that they sell, so they can sell gold. There's no bots farming T2 mats, because those are actually guarded by enemies so they'd need to constantly chug potions to stay alive. That's why they're almost all concentrated in the first few areas, which you would know if you'd actually played beyond those. But with an entire 50h of gameplay, as per your words, you've seen maybe 10% of the game world. It's alright to not enjoy the game, most of my friends either quit or are taking a break due to having other games they wanna play. But calling the game "dead" or saying it has had a "heavy" loss of player numbers, just isn't true based on any conceivable metric, except for the ones you make up in your head.
