That's why 99% of big-budget multi-player games use predictive netcode with rollback.

How a game like this exists in this day and age is beyond me...

To see rollback netcode in action, take a look at any FPS or a fighting game with GGPO-style netcode (this is P2P, but the concept is the same).

eg. http://www.youtube.com/watch?v=q0TZdY9_XHo

One client "thinks" the opponent opponent died so the "KO" sound plays. However, the opponent did actually manage to block in time so the match "rolls back" to a previous state and continues.

The worst part about this whole thing, is that if it's causing this many problems with simple encounter mechanics (to be honest, Titan, for example, is an insanely simple and straightforward boss, yet the fight is made hard by these issues), it's going to make any truly challenging fights with extremely complex mechanics and high damage attacks, and absolute nightmare. Basically the more challenging and complex Square wants to make this game (a good thing) the more we have to worry about it actually being a BAD thing, because its hamstrung by these ridiculous lag issues.

I think you're correct..my theory is that's why some of the people doing Turn 5 Coil at the moment think it's bugged. Can't know for sure as I don't know the strat, we aren't there yet (still working on Turn 4). A guild managed to down it (awesome job Blue Garter!), but they also said they felt sorry for all who are having latency issues.

In those games...players bitch about "rubber-banding". It is not as perfect as you think it is.

I play "those" games so I'm aware of the issues. As long as we haven't found a way around light speed and as long as people with crappy internet exist, there will always be problems. There is no "perfect" solution, but using a predictive approach with rollback is pretty much the standard because it alleviates many of the network problems that people complain about. It's unbelievable that SE didn't adopt this.

I fixed that for you. It's not that people choose crappy internet, it's that it's their only option.
