Question for Titan Ex

[BagelMagel]

So, I know that in Titan Ex you are supposed to stack behind titan to evade the plumes and landslides, I get it. I'm not sure if its because of my internet connection or not, but I cant seem to be able to evade the plumes when stacking behind him, so I usually stay way behind the group so that I can evade, and it works perfectly.
I was dismissed from a party in Titan Ex for staying way behind everyone in the party.

Is there any reason for me not to stand in that position? I mean how does it make it harder for everyone to dodge the plumes if the plume that lands on me is completely separated from the other plumes? If there is something I am not getting someone please enlighten me.

Edit: I'm making sure that I'm on the same line as the group is so the landslides don't hit at an angle.
