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

Yes, because I like to level up different loadouts of armour to compliment different exotics, so I've got a choice of what to wear depending on subclass or perks provided. I haven't worried about them too much for a while, but I've started to run low on Asc shards so I've started to do them again. Plus you need to be stockpiling them for when HOW drops, this is one of the reasons I stay at level 30 instead of going to 31. (I don't raid, so 32 is never gonna be an option)
