The OP only has a Level 30 CNJ/WHM... How can he know what any of the 8-man content is considering the 1st 8-man required event is a Level 40 Guildhest and the dungeons aren't 8-man until 49/50 (Cape Westwind, Castrum Meridianum, Praetorium, Ifrit Hard Mode, Garuda Hard Mode, Titan Hard Mode, Binding Coil)...

I'm sorry, but to me 'raid content' means 3+ Full Parties (Crystal Tower, Odin, Behemoth) all of which are Level 50 content... there is no 'Gated Raid Content' that the OP has even encountered.
