Why the netcode issue exists, and why it cannot be fixed.

When your client receives this information, it syncs to the time provided by the server

Why couldn't this read "When the server receives this information it syncs to the time provided by the client?" For your particular session anyway.

Anyway I have tested running out at the last possible instant with monster AOEs and its always right on. No issue here.

When the AE fires, the server is supposed to make its decision at that moment, not some time later when the client sends the next update. In theory it can wait, but that means even more lag. It's already laggy enough right now when the server doesn't bother wait for the next client update to render its decision. Imagine what happens if the server has to wait? It'd generally be in favor of players, but the lag will be even worse.
