Had that same issue for ages. No matter how fast I reacted, I got hit by those AoEs 95% of the time. Live in Norway (Northern part of Europe for those that don't know) and play on US server, not that that matters since EU servers are the same place. Changed from PS3 to PS4 and all the lag is pretty much non-existant. So if you have the chance to try on PS4 (if you're on PS3, that is), you should.
