Most low apm dps class and why ?

[SpeckledBurd]

I'll note that when people are saying APM here they're actually referring to Casts Per Minute which is the number of Weaponskills and Abilities they will use in a minute, while that's accurate for most jobs the Melee will all be slightly or much higher than the CPM suggests because of positionals. In a vacuum a Monk will reposition around 14-15 times in a minute to hit positionals which absolutely are actions/inputs even if they aren't being tracked as casts just as an example. That will obviously vary based on True North uptime(and Earth's Reply if you're a Monk), but even in the best circumstances you'll only eliminate 1-2 repositionings for non Monk melee with a True North useage, and Monk's useage is circumstantial to the fight (Best case Scenario is E2S where it has around 55% uptime at best, so still 7 additional "actions" as it were over the course of a fight).

But yeah Black Mage is definitely going to be the slowest of the DPS in terms of buttons pressed per minute.
