Blade dancer is just button bashing for easy 3-4 kills, fist of havoc gets 1 maybe 2 kills and nova bomb the same, so in my opinion blade dancer is by far the easiest character to buff your stats. Also I find a large portion of people who choose to play as hunter pick them because they associate "hunter" with sniping so you get all the mlg el1t3 360 n0sc0pez snipz try hard kids using them.
