Terrible instance netcode

The reason I'm not reporting this as a bug is because I don't really know if this would be considered as one; but more of a technical issue.
Since 4.5 launched, doing any sort of instanced content, be it Main Story Quest Instances or Dungeons or Raids, it has been incredible difficult to do it without getting bombarded left and right with 90k or 10105 errors to the point that I've been trying to avoid doing any instanced dungeons that I don't need to do. Alliance raids alone have been a chore because people having key party members (The main tank or healers) disconnect during the fight; sometimes getting disconnected again immediately as they return to the game or being locked out of the game for 5+minutes because of the 10105 error. It's disappointing that in most cases, when major patches release, the game's netcode has to suffer and it takes away from the player experience. I've never experienced so intensely unstable of a server as this one and it needs to be fixed; please.

Can't say I ever experienced something even remotely like that since I started around 2.3. Wierd

Never seen anything like this, ever, on PS4.
Sounds like the inherent instability of pc gaming and more likely a local issue. Try reinstalling the game.

Sorry, no issues on my end here. Maybe a random DC perhaps here or there every few months but that's it. MI player here so nowhere near the servers.
