There aren't solo PVE bounties every day, like today. There's just Crucible, Gambit, and team bounties. Yesterday there was one solo bounty, but I couldn't take it as I didn't have time to complete it until tonight after the reset. Last week I just barely managed to reach 5000 XP with five of those bounties, and this week I have less time to play. That's why that one bounty was crucial for reaching the weekly XP target. The game still doesn't do any favors for solo players.
EDIT: I miss the old way, when you could collect daily bounties, and complete them when it suited you. Now you have to play according to the game's schedule.
Why dont you just go in crucible solo?
Conflating PVE and solo is wrong (I say this as one who always wants Destiny to be more solo friendly).
