Don't worry/blame yourself for that mess with essences and their myriad of sources that SE has forced upon us. If you don't have the gil and/or clusters then just ignore other players, you can't be kicked out of DR anyway. Will the run go faster if everyone uses essences/actions ? Sure, but then SE should have made it way easier to acquire them. Also the there are way to many different actions/essences and their combinations to make this easy for the average player.
