Valid question. Here's another. Short of getting "access" to tier 5 loot (which doesn't kill any better, but does have more perk options so all the -blam!- drops can be "adjusted" except for every -blam!- thing over tier 3 dropping more often with -blam!- "handling" masterwork), what is the point of spending all your time in the game in portal activities, over and over and over and over, just to get to 450 (or whatever the current cap is) just to have all your gear, equipped and in your vault, be reset to 200 Dec. 2nd when Renegades drops? Assuming it does with the way the game is going these days. p.s.... the answer, in case you read all the way to here, is there is no reason. But then again, Bungie doesn't make this game for "real gamers" (console or PC), it is made for streamers and content creators who want insane difficulties to encourage "viewers" to join streamers (after subscribing of course) in game to get help with difficult parts and excite viewers in gameplay that looks fun so they will spend money on Twitch or buy the game and try it for themselves, or both ideally. Don't believe me? Check out one of the "sponsored" streamers ( although few will admit to being "kept" by Bungie) and see for yourself.
