Once I considered it's be a bad thing to lose a Destiny character (or all of them) but for PVE these resets where you need to go acquire completely new sets of gear have been happening throughout the game. I deleted a couple of characters a while back. One reason was to change appearance. To start a new character and run from start to end all of the Destiny story including all expansions, solo once you know the drill is about a weekend worth of time. And it's actually fun for a change compared to just grinding the endgame content. Destiny 2 will launch. We'll be able to run all the launch content in a weekend or less. Sure they'll likely time gate some of it, and then we'll complete that within hours. Even if you have a zillion hours spent in Destiny, The real time in character leveling is actually a small part of that. With D2, Bungie's basically deleting your characters for you, elevating an empty shell and giving you that fresh start. If they don't let you change looks as part of D2 setup actually deleting the character and changing looks is likely to be a small burden.
