Stamina and Luck are your friends. Don't bother with turrets as a Meister (maybe the push turrets, if you want). Go down the crit tree AT LEAST up to the 10% damage decrease skill.
That's all you need to do. Meister is a very easy class to play. Being able to solo 2-4 dark ninjas at level 108 + doing it quickly = lulzy and if you're another class then umad.
