As a solo player, and a mediocre one at best, I've just learned to accept that there is content and weapons that I will never get to enjoy. It's just another gun, I have plenty of others, and it's just a game, there are plenty of those too. I would like to get to play the other content, but not enough to do what it takes for that. I'm not going to blame Bungie for not making everything easy for me, but at the same time I wouldn't complain if they made solo versions, like timers and enemies adjusted per player count.
