Titan issues that need addressing.

[Izsha]

The issues you're describing have nothing to do with server-client lag-- they're entirely graphical lag caused by your computer. I know because I have the same problems.

The good news is, you learn to deal with it and compensate. I got my own Titan EX clear just a few days ago by starting to move a second or so before the cast bar even appears on my screen. Titan is a 100% scripted fight, so all you need to do is know when WotL is going to happen in his rotation and react preemptively.

So much this. I ramble and loose my points but simply put there are 3 separate issues that frequently get lumped under 'lag provlems'.

1. Graphical delays. Like described in op. Cast bar out of synch with graphic indicators. Hardware issue. Your machine isn't displaying the graphics fast enough. Dumb down your graphics as much as possible, or upgrade your machine. I turned of everyone's effects but mine months ago. I don't need to see constant flares, holies and dragonfire dives when I'm tanking, and neither does my video card.

Not lag.

2. Misunderstanding when the game decides damage. When cast bar is done you need to be safe. Not when the plumes actually explode. It's way to late at that point. Solution: make cast bar gui bigger and move to prominent place. Learn to keep an eye on it. (SE could adjust timings of animations to be more intuitive, but until then learn the game as its currently designed).

Not lag.

3. Lag. Check your wires, router, etc. Bug your isp if it's always there. Try stuff like wtfast. This is the hardest thing to fix. Lots of googling solutions and prayer needed.

It's lag.

Most people's problems are 1 and 2. If you fix 1 and 2, you need absolutely nightmarishly bad lag to make this game 'unplayable'. People play from Europe and function. People play from Australia and function. Chances are if the game is 'unplayable' for you, then you have a lot of 1 and 2 going on. Unplayable lag is really not that common, but other problems are mistakenly lumped into lag. Check everything else before you throw up your hands and cry lag. In most cases it's not.
