I've never been killed by lag on Titan. Every death that I've had was 100% my own fault. I either didn't move fast enough, or made the wrong choice when I was moving out of an ability or casting a spell.

I know that people constantly say that lag is killing them, but a friend of mine put it best - "That's 'Post-Bad Decision Lag. It's an epidemic in this game!'"

Tonight I died on Titan because bombs came out and so did landslide and I had the choice of running into the bombs about to explode or running through the Landslide to the safe side. But that death was my fault. I made the wrong decision. It wasn't lag or anything else.
