Random thoughts after my second VOG clear and on the eve of the expansion:
1) VoG is still fun even if it is about to become marginally useful.
2) VoG should still be the easiest place to get the flawless raider trophy even after the DLC drops and elemental primary weapons will still be very handy for Nightfall missions, even at lower attack ratings. (Atheon's Epilogue, Vision of Confluence and Fatebringer, gotta catch em all!)
3) Killing a raid boss should never, NEVER reward only 2 ascendants and a shader. That is just poor.
4) I'm still not happy about the exotic upgrade plan. Anyone who is siting on level 30 by using an exotic will have to de-level to 29 in order to take their exotic past 30 light because of the trade-in program. Congratulations on being less useful and powerful while you grind out that 300,000+ exp!
5) I got a raid chest last night in only my second VoG run. (Lucky me, right?) Combined with my exotic helm and the IB gloves and boots I could hit 30 this weekend if I wanted to. Except that spending an exotic shard on my helm at this point would be asinine (I had all but the last bubble filled in) as would spending shards on my new chest that will most likely be out of date come Tuesday.
6) Destiny is still really fun but some of Bungie's decisions about their game make me shake my head in bewilderment. They have A LOT to learn.
