It would be very cool to have weather features in Destiny!! However, not trying to be a pain in your backside and the need to know value of this comment is probably .05% but I thought I'd let you know Earth is the mainstay of the fallen, Mars as you stated is for the Cabal, Venus is for the Vex (favourite enemy), and the Moon is the mainstay of the Hive. But as I said early I totally agree and it would be an awesome feature!!
