I have this crazy belief that everything should be accessible to everyone in this game. Regardless if that players owns the DLCs. Notice, I said accessible, I didn't say EASILY accessible. You could argue that E-Light is technically accessible to Non-DLC players via IB and Nightfalls. But the droprate in Nightfalls appears to be laughable and IB is such a horrible chore. I grinded the last IB and hated every second of it. I'll likely do it again at the end of the month. But I hate chores. Just ask my mother how likely I was to do them growing up.
