Well why would you continue to play if you feel the game is monotonous and boring? There's plenty of games that revolve around repeating activities in order to progress, in fact most mmo or rpg style games are like this. I will agree that there needs to be more strikes, raids and story missions but I also think people need to get used to the fact that even if there was more content we would still be repeating it over and over again lol. Also if you compare destiny to any other AAA fps game on the market right now you'll see that destiny has more content than most of them. A 20 hour campaign is pretty long compared to COD or BF4.
