From what I saw lvl 30s have a considerably easier time on the hard raid then lvl 29s. One lvl makes a huge difference on hard, but if the lvl 29s arent totaly bad then with propper weapons they should be able to defent the conflux. Also Hunters seem to be decent in in the gates with the golden gun. Ive witnessed on my Normal run that ppl are very bad even in PVE... Two dudes on same level as me died over and over again while me on my first VoG try defended a pillar alone lol. With no raid weapons... :)
