It's just SE their servers and coding,not your latency.
Yes if you have 20 ms it's a bit better than 200 and it will allow you to dodge the stuff a but better.
How ever it doesn't remove the fact that you play with a delay of 0.5 to 0.7 second by default.
Bit if lag and you're screwed.

While latency occurs in every MMO it tends to be masked better than this.
Take WOW I can play it with 100 ms to 150 ms and don't encounter the massive delays I have in this game.

SE did accepted this as a bug so we'll see if they fix their servers.
Other wise you just have to eat it or learn how to work around it.
