Longevity of a game is partially determined by the amount of random luck, that manifests as grinding, inherent to the game or a true grind that guarantees reward. Too much will cause players to give up, and too little won't keep people around long enough for the game to be memorable. The gaming world is evolving. There used to be a stark difference between fps/action games and rpg/strategy games. The two are being fused like never before. With that comes the good and the bad of both worlds. Players new to rpg style RNG and grinding will hate that aspect of the game, but they will understand achievement as it is respected in fps and action games. With that said, in a past post I calculated that a specific exotic had a mean time to drop of about 2.5 months if you ran both raids on hard with all 3 characters each week (6 chances per hard raid, 3 characters is 18 chances per week). I was lucky enough to have gotten a Gjallarahorn, but I still need Red Death and Hawkmoon. I complete all raids and Nightfalls each week with no reward. It is the only thing that keeps me playing (plus for longevity argument). However, I am growing weary and bored and have debated quitting on several occasions (plus for RNG killing the game eventually argument). This is why I suggested removing vanguard mark caps and allowing a vendor to sell exotics for 1000 to 1200 marks. It will still take the mean time of 2.5 months. However, now you are guaranteed to get what you want. It will gives players a light at the end of the tunnel without flooding the game with exotics effectively sustaining longevity and removing the weary boredom that RNG creates. On a side note, Deej stated in an article that Bungie's intention was for us to obtain every exotic. At first that seems like a feasible task because they are all new so every drop is a breath of fresh air. However, when you are down to 2 left with no way to influence RNG. The statistics suggest it may take a year or more two finish the task they claimed they wanted everyone to achieve. Like I said above, let us grind it if we truly want it. RNG is good, but it can be cold and salty. Let us feel the sense of achievement for a hard grind instead of misery for not being lucky.
