Sorry SE, but endgame won't work if you don't fix something.

Man I love the threads of bad players blaming lag on their deaths for titan HM. Even if it was lag (which 90% of the cases it isn't), that fight is so ridiculously easy and predictable that anyone with half a brain can do it. Here's a tip, watch the HM fights on Youtube, grab a pen and paper, and write down every single move he does in the order it appears. That will never change. Congrats, you learned how to anticipate Titan's Weight of the Land before it even starts!

Edit:
Here I'll do half of the work for you~
[After Heart Phase]
Turmult
Weight of the Land
Bombs
Landslide
Weight of the Land
Landslide
Repeat~
(I don't include Mountain buster because that's only something the tank needs to worry about)

After his heart breaks he'll open up with Turmult, if your SCH hasn't gone full retard he'll have dropped Sacred Soil to mitigate the stomp damage. Immediately after stomps finish, begin running away from titan because he's about to pop Weight of the Land on the clustered bodies that were attacking him mid stomp.

Landslide and Bombs are self explanatory and I really shouldn't need to explain any further, if you get hit by those, just go save up 700k and buy yourself the win.

After the second landslide have your SCH ready to drop Sacred Soil and repeat.
