yeah dude you're right, this game infact all games are about having fun, you shouldnt GRIND for the exotics you want, you shouldnt waste hours and hours on that one vanguard roc or tiger strike and hoping RNG to drop an exotic. Dude enjoy the game and you will be suprised of the reward at the end of the stike, nightfall, raid ect. Do the activity for the fun of it the reward at the end is just to reward you with the hard work. I enjoy this game so much, and the rewards that i have 3 characters, and when complete every activity i delete my 3rd character. Make a new one amd rank it up to level 20 again and do every activity all over. This is what i do every week, i dont grind the game. Just have fun.
