My fastest time to 20 is around 8-9 hours. I'm no Destiny leveling expert but I thought it would be nice to start up a little guide. I personally crucible to level 4, pick up bounties, then just follow the story doing bounties along the way. I don't do Strikes unless I have the bounty for them. I'll edit this as we go but I ask you post 2 things. What's your fastest time to 20 and what are some of the tricks you use to level quickly.
