Very simple. The lag in cyrodil has not been fixed. zos is still trying to get people to spread out. But now they have taken it a step further. Reduce the number of people in one area/quadrant. How you may ask? Well, in ZOS infinite wisdom they probably believe that if there are less people on the battle field due to instant dying and more people running back on horseback then In theory the lag will decrease.
Which is why they introduced an op instant win destro ult. we all know that the destro ult is the ultimate Zerg buster because it wipes zergs fast. More people dying less on the battle field.
So. I believe ZOS has a real problem on their hands. They are fundamentally trying to change the core combat mechanics to combat the lag. However, no one likes a game that uses luck and rng over skill. Now they are stuck.
Folks, it's either lag or instant death. Pick your poison.
