For the last few months, I've been fighting against your model above. With zero success.
My 8th has a rr holy burst pg longbow [so its normally 10th lvl item?] and as much as I want it to work better than melee, I still find that dropping the bow and jumping into melee with 8th lvl weaps is more effective.
The only more effective use I've found for bow attacks is to deliver cursespew/destruction/para before the critter gets into melee range.
So yes, ranged is broken.
