This post is for both experienced and new Lvl 50s, and I sincerely hope it helps you with PuGing (pick up group) Titan. I'll break this post down into two versions, one for experienced players, and one for new players--->

Experienced players:

1. Use macros. My god, I cannot emphasize how much this helps with pugging Titan. Not your rotation macros, but simple macros that spell out Titan's skill through each phase. Here's a copy and paste version of my macros:

/p <se.1> Turn 1---> Landslide, stomp
/p <se.1> Turn 2---> Plumes, landslide, stomp
/p <se.1> Turn 3---> Landslide, plumes, bombs, landslide, plumes, rock, stomp
/p <se.1> Turn 4---> Rock, landslide, plumes, stomp, rock, landslide, plumes
/p <se.1> Turn 5---> Table, stomp, plumes, bombs, landslide, table, plumes, rock
/p <se.2> Plumes!! Care!
/p <se.5> Determination de-buff on <target>
