Most players have a ping in a range of 130-230 on EU server (I played from several countries in West EU, East EU and Middle East so it's a validated information)
ZoS building up ESO at 0-20 ping (building, because it's really hard to call a finished product)
Now how do you feel that as a normal player?
Did you ever notice how you die outside the bosses AoE attack? Like your corpse lying out there just 1m out of the AoE telegraph and you are wondering how that happened? Well if you ask your teammates they will tell you that you are 1m inside the AoE.
Or you are running to hide in vFH behind column and you die when on your screen you are 100% behind the column? Well if you ask your buddies on their screen you are not.
That's your ping and ZoS's incompetency to deal with it.
There are many places like this in the game where players feel the full wrath of that 0.2s ping getting them. Mostly this is the instadeath places of course. Like Selene's bear attack before it was nerfed 10 times.
And now there's also another side of that poor optimization:
Synergy. Every time you want to pick that shard with 0.2s ping you have to enter the circle, wait, pick it up. But there's synergy indication swap between the players which simply causes noone to be able to synergy that moving orb out there, something that is really to notice if you are dedicated observing player.
@ZOS_Wrobel , it is about time the telegraphed AoE and "real" had to be separated and compensated towards players with 200ms ping. That means enlarging the telegraphed circle of instadeath AoE's by 1-2m (or decreasing the "real" by 1-2m). And increasing the telegraphed circle of Synergy AoE's (like shards) by 1-2m. So when someone actually enters the circle on his screen he won't feel that 0.2s
And yes, if you want to develop hardcore games 0.2s is huge value. Cyber-athletes in competitive game would never challenge each other with difference in ping of 0.2s.
