Sure, maybe you're just not good and need to spend some time understanding your build and how to use it or make it better. But, I see a lot of frustration in zone chat particularly when it comes to being wiped off the map or being unable to sustain when others seem to be able to sustain endlessly against multiple players and dish out damage. I've talked to a number of people via whisper as well, about how it seems like no matter what they do or how long they practice they just can't get an edge.
I'm just writing based on my experience. I've mentioned before I play a loonnnng way away from the NA servers (NA is where I started), in fact it's just about as far away from them as you can get without starting to go back around the world. 80% of the time my lag is terrible, constant health desyncs, or something like I'll drop a dawnbreaker and stun the guy then go in for the execute and my LA+executioner simply whifs, a total miss. Why? Probably because in reality the player has since broken free and isn't exactly where I think they are on my screen, or the system simply isn't registering my attacks. Whatever, its just a fact of my life, just giving some background.
Anyway, about 20% of the time, when the stars align at the right time of day, my latency drops down out of the red and the game starts to function as I would expect it to. When this happens it's like a light goes on and I get a bunch of sigils from vMA or something. Sustain suddenly starts working, it's no issue to kite players, AC and fast strings of attacks start working, ultis fire when I need them to instead of after a person heals to full. All my hits connect. I can sustain against multiple players on my own (barring some of the better more well known ones of course). I'm not the best pvper out there and im not trying to be, and yes we can all get better. But don't underestimate the effects of your internet connection and/or hardware on your playing in Cyrodiil especially. There are some players in Cyrodiil who do know the game really well. Those are the players who you cant probably beat no matter what. But for your average jabs spammer who seems to have ungodly healing power, and you cant burst their health down for your life, probably lag. So, don't beat yourself
