I liked it. I mean yeah it was tweaked replay of content, but it was basically Nightfall versions of story missions, which I thought was cool and with a guaranteed legendary drop the effort felt worth while. I'd much rather do that then grind out strike playlist for blues.
The gear needs to still award shards though if dismantled. So lame they removed that.
And the rep grind for gear would have been cool if it was even attainable.
Eris is basically the quern anyway, minus the kill missions
