It seems to me like tanks take the brunt of criticism above all other classes. But the whole point is to work effectively as a team. As a newly inducted tank player myself. I've learned a lot in the few weeks I've been playing. How you utilize your skills is something completely up to the tank. So long as it is effective, and it keeps mobs off my party members I'm happy. I mark my mobs, I cast flash 3 or 4 times in the beginning to makes sure I've got aggro on me, shift+F for my focus target and switch between the one's I prioritized. If an add pulls away, I use provoke or shield lob to bring it back in, then cast another flash. Of course, I'm always adapting, you never know what dungeons have knew spins lying in wait. But a tank won't get better with snob or snide remarks. So it's good that you elected to put in some constructive criticism.
