no one was questioning dlevels effect versus low level mobs, I was questioning two things
If dlevel negates gear/stats
and how much does dlevel effect things in the range that you would be expected to attack them basically from -5 to+2o levels
then, how effective are your stats in this range.

I dont think any one really cares how much they can own a rabbit, or how much dmg a level 99 mob does to them at level 50

but beyond the discussion of dlevels effect in those cases, since we have no formulas, it would probably be better to discuss what type of effect you expect being well geared to have for your level because that is quantifiable.
