Titan isn't anything more then a focus Check.

Can you stay in line for 5-15 mins without anything going wrong.
Don't panic.

Only really check on anything is heart. If you can't get heart you are in trouble, This could be for many reason. DPS not putting Dots up before breaking jail is a easy one to miss.

I'm 3/3 on titan in 2.1 I was about 0/50 in 2.0
