Pre the DLC, I would make sure I did the daily in an attempt to get Ascendent Material to level up my armor and weapons. Post DLC there's really no point to do the daily missions especially if your weapons are already maxed out and you have the new Raid Armor. I haven't done a daily in a while and the only time I do is when one of my friends is doing it, but I just usually join for the conversation

No, bounties are my daily now.. I'll only do them if I get a new exotic armor piece that I want to max, but even then I check to see which mission it is... If it's a Dlc mission or "the archive" I generally don't do it, just because they're a pain in the ass.
