Totally agree, I haven't actually done VoG myself and it's kind of annoying that it's pretty pointless for me to do it now. At the moment it's as if the raids are timed content and if you don't do them before the next expansion drops you'll probably never bother with them. The way I think it should work is that normal mode should remain the same with the same gear dropping and the hard mode should always scale to the current light level cap with any gear scaled to the current max (armour would have max light level and weapons max attack rating). That way you'll still have some content for new players working their way up for the first time, but you'll also increase the amount of content for endgame players.
