It used to be that we had a 2-3s window (between the 2nd to last, and last tick) to refresh expiring dots in order to not lose dps.
Now, we have 7-12s windows, which will overlap, allowing us to break channeling, apply 2-3 dots, and then go back to longer channels, as compared to breaking channels more often to refresh dots, giving shorter periods of channeling.
