No, good point! That's the only thing in the game that has a guaranteed reward of 3-9 coins. You use those to trade with Xûr who has a somewhat randomized inventory. So you can at least get an exotic weapon and upgrade it for the Trophy/Achievement. There are only two exotics you can get from raids. Vault of Glass gives you the Vex Mythoclast, Crota's End gives you the Crux of Crota/Necrochasm. Both weapons drop from Bungie's dark RNG Magic regardless of skill in their respective raids. So any other exotic you find, isn't necessarily tied to the raid completion, but just a bonus. Bungie has stated that [b][i]"there are many paths to exotics, all are valid." [/i][/b] I think we can all agree that Destiny's RNG is probably the worst in a loot driven game, ever. You should receive the best rewards for doing the hardest content (which you can, you just usually get a crap reward instead). Not AFK-ing in crucible or vanguard strikes.
