IO's came along after I quit Live, and I've spent the last couple of days trying to make sense of enhancement sets and attuned IO's. My main question at this point is that if I am level 50 and considering a set that has a level range of say 30-50, is there any reason I wouldn't buy the attuned level 30 version? When I slot it, it should take on the attributes of the level 50 version, correct? And it should theoretically be cheaper, or does that not come into play due to the "bucketing" that takes place in the market?
