Lag for me is much worse than it was 2 years ago (haven't been played much in the last 18 months until the last month or so, I've been on actively again).
The worst is when I am hunting, massive numbers of failures in a row, complete lag outs while shooting/healing/swapping, etc. It's really annoying when I'm hunting big mobs, where healing is crucial, and I'm jamming my hotkeys and nothing happens for a solid 10-15 seconds. Then the lag stops and I'm down to 1 HP and barely getting my regen chip off in time. The other issue is while shooting (using auto tool, of course) it just stops, even if I click the mouse nothing happens. 10 seconds later, my gun will start firing again.
This is the type of lag I remember dealing with in pre-gold, and its unacceptable. Oh, and guess what, I've rubberbanded a few times lately as well (mostly while flying). I haven't seen that in 7 years...
I'm using a high quality service provider with a 50mb broadband connection, and I don't lag in any of my other online games (Wildstar, Planetside, etc). So, I highly doubt this issue is coming from my end.
Still love this game, of course, but some of these lagouts become irritating when it's frequent.
