I'm going to say a few things.
First off, this game was sold to the wrong audience. If you don't like repetitiveness and grinding.. then sorry.
I have three different 28s and hardly ever play PvP, I quite dislike it without friends to dick around with. I am having the time of my life playing the PvE. I don't see myself getting bored with Destiny for atleast a year.
The whole thing on the loot system.. I think it is perfect. It works for this game. Just don't have the expectation of progression through RNG and you shouldn't have a problem. I see tonnes of people on reddit crying that they're stuck at level 24. The replies everytime.. grind your rep and buy your first purples.
It is satisfying when you get an exotic with this loot system instead of everyone having all of them. I have yet to find an exotic and I can't wait until I do, I will literally scream. The exotics I do have, I either bought with the coins I earned, or gotten them through bounties.
Sorry, got a bit ranty.
But if you have this many complaints about the game(not you guys, the community) then put the game down. It clearly isn't for you. This isn't like MMOs of the past. This isn't like Halo(the PvP). This is a first of its kind in genre. MMOFPSRPG blah blah. No one can pinpoint what exactly it is.
Just my thoughts I thought I'd put up. Sorry if it offends anyone, not meant to.
