Because if your decent you should be at least 31...I have no problem letting 31s into crota HM but 29s into VOG HM ...its SOOOO easy to get lvl 31 and if you don't have the skill to get to LVL 31 by now and your still 29..chances are you haven't even raided yet..at least that's my experience and yes..I do remeber running VOG with all 29s, hell I used to have 3 29s because back then 29s were excellent players mostly..just like 31s are also decent, maybe not as much tho as it was harder to get the VOG armor than it was to get the CE armor..anyways that's why I asked for 31+ cause most the time I don't have the time to deal with some kid who doesn't even know what a raid js and just bought the vendor gear
