There is a place where lvl 4's can compete with lvl 30s and have things on or close to the same level. That place is called the crucible. Why make another crucible? Would you expect a level 4 to be able to complete the hard mode raid and kill the lvl 30s easily? No. Then the same damge relationships should exist in the Iron Banner. Enough with the "power matters but so does skill." If I go into Iron banner as a level 4, it should be as impossible as going into hard mode raid.
