At the absolute very least they could simply add .33seconds to end-game boss AoE for a while. It's broken as is, and feels terrible.
Longer term, I don't see why instance servers can't poll more frequently than .33 - In the open world, I get it. But if i'm being given a dedicated instance, why can't the instance server poll more often?
The system, as it feels, is essentially: player presses a button. Client asks the server "can I do this?" the server says "yes, son", the client says "cool, i'm doing it then daddy!" and then the server says "No running with fire!" and the client says "but I wasn't" and the server says "Oh sorry I hadn't realised you'd stopped running, I was reading Nuts magazine"... etc etc.
