Why the netcode issue exists, and why it cannot be fixed.

[Garnatian]

latency can have different issues. distance is one of them, yes. however, the ping to Montreal for me are better than they are to the european (!) servers for SW:TOR for example. I play on a US server (ping ~180 to 200 usually), and I never ever have any issues with dodging (and timewise it's often a lot shorter in that game). I play tsw on a server located in NA, too. lots of aoe to dodge, no problems except 'derp'.
I play PS2 relatively competative on a US server. I know my legitimate server distance lag.

ARR?
not a chance. a ping of 120-140 does NOT cause this latency. people with a ping of 20 (!!!) have the same issues that I have.

european servers would not 'vastly' improve the issues, but be a waste of money SE should spend on actually changing the system. they need any penny/cent for it.

Where are these people with 20ms ping complaining about the issues?

As for your comparisons to SWTOR, I call bull.
