As far as dungeons is concerned, it is perfectly acceptable you tank all the trash mobs in between bosses in shield oarth. In fact i would recommend that you do. As for bosses starting out with 1 enmity combo in shield oarth then swapping to sword oarth is usually sufficient, however if you are much lower geared than the dps, you might have to do 2 or even 3 to stay ahead.

As for getting confidence the answer is simple, keep at it, practice, you will get better at it and gain more confidence as a result. If things go bad don't take it to hard, explain to your group that you are new at the job and most people will understand. For bosses, rotation wise just practice it and you will get it, basically you can forget the enmity combo exists outside of the pull, once you have established enough aggro at the start of the fight, you should use only the dps rotation which is: Fast Blade > Riot Blade > (Fight or Flight) > Goring Blade > Fast Blade > Riot Blade > Royal Authority > Fast Blade > Riot Blade > Royal Authority > Fast Blade > Riot Blade > Goring Blade > Requiscat > Holy Spirit x5 > Start over from beginning. Use Circle of Scorn & Spirits Within whenever they are available, and shield swipe whenever it procs. Use defensives for tankbusters or periods where you take a lot of damage, but generally dungeon bosses won't hit you hard enough to make this an issue, you should however use defensives on trash pulls.
