Answering the question about the fun of DPS, well my other main is MNK so...
Monk is based on a combo u need to keep up, while avoid AoEs and hitting the enemy on specific spot, the longer u keep the combo+dots the most dmg output u have. And the faster you kill, less the tank take damage and the less the healer needs to heal so...cant drop the combo =0

I changed from SMN to SCH (even loving Summons) cause...I felt more like Healers r the ones that have to deal with more adversities, and the one that need to think faster...so yeah its an adrenaline bomb. Criticals n Primals AoEs (Titan anyone?) r godd example of it.

Im thinking on WAR n BRD as 2nd class of my both characters, liked them both :3
However I would prefer if Bard was Archer/Conjurer/Arcanist ._. being a DPS buffer was so cool on lower levels at least XD
