I think if destiny adds platform puzzles to the game there would be alot more diversity in the game. They first implemented this concept in house of wolves I think the gamers will really enjoy a 3 dimentional megaman/super Mario style gameply on top of what we already have . I also enjoy hazards in the crucible like disappearing platforms teleporters those taken shields that push 6ou out of cover the psion ball that push you I'm the air hive traps and hive wizards shade attack Just some ideas
