How much of that vaulted content do you actually play? I can understand the argument about Leviathan activities going away, but they've been labeled as legacy content now and gear awarded from them are getting sunsetted come next season. I've been playing release and I honestly have not cared about Mars, Io, Mercury, or Titan(may as well vault Titan since they it's a wasted potential) for a long time now. I hate Mars because of Resonate stems that I can't delete if I don't have 4, Io is just pure boredom, Mercury is just pointless, and Titan isn't gonna get an explorable Arcology. The point is, the game is getting too massive and a large chunk of the game has become obsolete and irrelevant. Game download size plays a major role in one's decision to download a game, and I'm sure there are potential players out there who are waiting for the game to reduce in size before giving it a try.
