I did POTD 51-60 on the 16th for the whole day and can count the runs which took over 15 minutes on one hand. SAM's and RDM's are great in POTD with lots of burst. And both classes have plenty of heals... RDM has cure and SAM has Merciful Eyes, Bloodbath and Second Wind, and both jobs have potions. As Yoshi-P would say, git gud.
