The guys on the plates have three jobs (maybe 4)... 1. Throw a grenade at the ogre that pops next to your plate (some titans like this because it flinches the ogre) 2. Turn and crouch at the back of your plate and hard scope their Knight that appears opposite corner of their platform 3. Kill any and all acolyte eyes that appear if it's feasible without risking your death 4. Get back to the middle. Rinse and repeat. In my opinion, doing titans up top runs the risk of the knights making it to the bombs. Especially if that strategy is the least used strategy and most likely needs to be explained most of the time. Titans need to kill the ogres and the fourth Knight (unless someone can manage to kill it) and stay alive. The runner gets the spark and kills the vessel and shoots Oryx and stays in the middle when the bombs are being detonated.
