Drg and Mnk play very different. Drg is slow big hits, and Mnk is fast little hits. My mnk with 4 i90 pieces including relic+1 has never broke 700 damage on a crit. My fresh to 50 drg with titans spear, DL acc and AF broke 1k crits first time in AK.

Drg has more abilities they use on a regular basis but their uses is more strict(combos). Monk can use whatever they want as long as certain conditions are met.

I like both but for farming purposes my lower geared drg is WAY better than monk.
