Titan HM doesn't like me.

You have to be out of the AoE when the cast bar finishes. Not when the animation goes off. Not knowing this is what kills people most of the time and they then blame lag.

Also zoom your camera out.

Lag is a real problem. I play Titan HM better on a PC rather than a laptop, for instance. Small amounts of lag from the system or the internet contribute to making the AoEs hit inaccurately. I've experienced it before and so have others. You clearly don't, so good for you.
