10 3 of coins is like 2 exotics vs the 1 exotic you could've gotten from the nightfall. Seems legit to me. That and with an exotic engram, you can switch it to the character you want it on, and influence it's light level by having all your characters at at least 300 light at the same time. So you get to choose which class exotic you get, you have a greater chance at a 310 light level exotic, and you can get 2-3 per 10 3 of coins. Yet you're [b]b[/b]itching.
