Okay there is that pug Sage dps in the group. I realize that he's Telekinetics spec'ed but not using the correct rotation; as a matter of fact, he doesn't even have one. As the other guys are guildies, I tell them to stop a bit because I want to help this dude.
I /whisper him what to do and at the end I say "Basically spam Disturbance until you have 3x Concentration or you get a free Telekinetic Wave". We continue but no changes.
I /whisper again, "Dude spam Disturbance".
After a rather long pause he replies back, "Yeah but I don't have spam in my skill tree".
