Give the essential minstrel a chance
In solo, Burglars can kill enemies one on one and get away with it. In fellowship play, they should be the conjunction experts, knowing when to trigger one and what colors each player should pick to get the maximum benefit and then they should just wander around, stabbing from the back where possible and performing a general CC role. If Phoenix Dynasty Gold all goes pear-shaped in an instance, Burglars have enough skills to give the essential minstrel a chance to get away.
