I personally would like to be able to create at least 5 characters instead of just 3 because if I wanted to start over and give myself something more to do in destiny, I have to delete one of my characters that I have spent hours on. Of course keep the amount of times you can do the nightfall/raid to only 3 characters a week. It would give dedicated players something more in destiny than to just do extra side quests (that give us uncommon rewards) that we never completed when we first got them so they don't give us a reward that's worth the time we spend on the quest. It would give us the opportunity to go back and relive those hard missions we used to do when we had just started.
