i have invested some 750 hours in our favorite class and i got some of my items for free (a 1.2 beez cala, 200 m dml, 200m nats boots and a 4.5 cc 9 ias mempo) and the rough estimate of my gear is about 4 beez (including my alternative gear - cala, nats legacy and over 10 SoJ's and ... a lot more)
my first dh took 500 hours to get to 100 (mostly cause of lame gear and slow lvling before reaching paragon 40) and my second dh is about 90 hours in with para 66 and i ahev another dh prepared to be leveled after this one gets to 100
i tried countless builds (ea, hungering, cluster arrow, scatter, bola/st, rf and so much more), favorite being the irreplacable ''nyan'' build (modified for my own prefference) and the classic bola/st build that i'm using atm...
currently my average xp/hour is about 120 m (regular festering + fields) on mp8
so... start raining criticisam on me :P
