Adapting to the support role is simple. Don't actively steal CS or kills, and drop wards. Other than that, just harrass the enemies and don't die, just like in any other lane. It's not hard, so I don't understand why people get so upset about it. I guess most people want their personal glory and their egos stroked off in a team game?
Also, the ghosts are better on the FQC because they're designed to scout for nearby enemies and hinder opponents so that your ADC can hunt them down and kill them. They're not for engage, and in fact are poor for engage.
Meanwhile, FoTM is designed to be a tanking tool. It provides you and your ally with shields to keep them from death and to give you better longevity in team fights. Most tanks have an engage already, so a shield is infinitely better.
