So, i just found out that if i boost my friend in IT for example (thats what i did) we had a 3rd member in our group (lvl 2 at that time, in the starting area before he entered the world) and when the item droped from a boss our lvl 2 guy could roll on the item as well (and could actualy recieve it) this might would work with other instances and even raids (thats a theory tho)
Step by step
1: go into IT
2: have the guy who should get the item in the starting area (1-6), (might work outside in the world as well, but havent tested)
3: kill the boss
4: let the guy whos low lvl roll need
5: ??
6: profit
THEORY
if u can 4 man an 50 instance or if this works with masterloot you could fully gear an low lvl with full 50 raid epic if your guild can manage 19 manning it (but thats a theory)
sorry for my bad english
