I have no issues with so-called jig-lag unless I am simply not paying attention and forget to jig. Early on there was some UI lag that could cause jig-lag, but for me, when I press the button on my controller, the little bobber thingy stops. Unless I just blatantly screw up I have no issues what-so-ever hitting the same spot I just hit.

Problems occur when: my system does something like auto-download an update and start to install it, I open or close another program (like Word or Photoshop), i.e.: the usual suspects. Playing on a clean system (Win Ultimate, fresh install, with uTorrent, Word, and Firefox, a recently reformatted drive) and having turned off all background auto-updates and turned of services I don't use... no problems.

IMO, 90% of jig-lag is caused locally and is fixable. (That's a figure of speech, not a hard number!) That said, I won't dismiss jig-lag as an issue that SE needs to address. As it is, you DO have to pay very close attention. If someone asks you a question and you answer it, you will end up passing your jig timer, and loose your fish. A system like this is very touchy, and I can see how any amount of lag could be a problem. Especially for those of you on cable. Neighbor starts to torrent 50 seasons of SNL and the next thing you know, you loose a fish. SE definitely need to build a little more forgiveness into the system, reduce keyboard and mouse lag (I play with a controller because it is so much more responsive, but I can't wait to get back!), and all that. IN the meantime... Do what you can to maximize your ability and clean your system up. It is well known that harddrive read-write especially bottlenecks FF14.
