To those saying other games aren't suffering the same issues : maybe not for you.

Quoting WoW forums (US, since I suppose that's where most of you are) :
"Lag.... game is UNPLAYABLE."
"Extremely high world latency."
"Constant disconnects, game freezing, lag"
"Unplayable lag spikes."
"Constant stutters and terrible latency."
"High Latency for Comcast users part #2"
...

GW2 :
"lag lag lag"
"delay and lagg"
"Connection error(s) detected. Retrying..."
"Darkhaven server lag"
"Unplayable lag on specific game server IPs"
...

D3 :
"Constant Lag"
"LAG"
"latency issue"
"AT&T Related Lag/Rubberbanding Issues"
...


That's fine, maybe you guys have no problem running these games. Now please, just stop quoting them as models when they currently have the exact same problems as FFXIV for some of the user base (just like FFXIV). And what do they ask to fix the problem ? What Raist said.
