Chicken nugget (as me and my friends call the Titan-egi) has been one way how we did Mog Ex when we were bored and didn't have a second tank.
You can also do the same with the fairy as SCH in Titan but it's nice to have the heals centered for that Rouse+Whispering Dawn+Fey Illumination. Honestly, anything is better than putting your stupid pet in front of Titan. Stop people. Seriously. move that shit so it doesn't get hit all the time and you can focus on healing/damaging and not healing your pet :V
