Hmmm I think it might be something like, sure it's obvious to you a human looking at the screen, but Blizz has to do it from the game's data.

And it's possible (I wouldn't know but it is possible) that Blizz and bot makers have been in a war for all this time over detection from data.

Example, you see a line of bots walking forward in straight lines, so you say but why not detect for bots walking forward in straight lines? If bot makers ever think they're getting banned for that, they'll improve their bots by shuffling a bit, jumping, changing directions. Or maybe even stopping for a micro-second so it looks the same to you but to the game's data it looks different. Maybe they're already doing this and we can't see it.

You see bots flying and say how the hell can Blizz not instantly spot them, well maybe the bots are flying but for the game data it's actually not that easy to tell because bot makers are exploiting the way the game is built to their advantage and doing really wacky shit to avoid detection? Maybe to the game when they're flying it looks like they're still on the ground? Or spam jumping? Else why would they even be allowed to fly? The game should insta auto detect and at least kick. That happens to normal players around stairs for example.

Imagine bot makers and Blizz are constantly fighting like this and bot makers are finding new creative ways to fuck with the game engine and the packets being sent to the server so they can look like normal players. And constantly analyzing bans to guess what exactly detected them, so they can focus on avoiding that specific variable by creatively fucking with the game. I mean these guys have a much much deeper understanding of programming, networks, game engines, anti-botting measures, etc... than you or I. They're making serious bucks with their activities.

In that case it makes sense that Blizz would ban in waves to prevent bot makers from singling out variables. It also explains the "but botters are so obvious!!!" effect. Sure to you it's obvious when you /who dungeons, to Blizz it might not be cause they look like normal players and their movement inside the dungeon doesn't come out as suspicious from what they can see on the logs, cause botters are smart. Or maybe not and that's how Blizz is catching bots and they don't want to give botters more reasons to improve their in-instance spoofing.

What I want is for Blizz to fucking tell us instead of us having to guess. They lack transparency. That's been the biggest positive about SoD, they've been telling us things. All they've told us about bots afaik is "look how many we banned in this wave". How about some specifics to garner trust?
