If 300ms (pos check delay) on top of your 20-200ms (depending on your location/isp) is not lag, then i do not know what is. Id guess my ping is around 400-500ms with this ridiculous netcode, and that stands for all of us european players. I certainly get hit ALOT when im already out of the ring. I need to be out of the AoE for just around 0.5 seconds before its cast or i will get hit... and that is certainly alot. But as ive said before, this game would be far too easy with no lag.

Im guessing the OP is american since hes not experiencing as much lag as alot of people are. Might just be a troll though. I mean, HOW on earth can you state that the problem is our ISP when theres an automatical extra 300ms on top of the real ping... have you experienced 300ms+ in any other game? Try playing an FPS game with that ping.
Well, gladly this game is playable with ridiculously high latency..
