[b]Edit: Bungie announced via Twitter the you can purchase every twelve hours. Thanks for clearing that up.[/b] So I have significant problem with how the Tempering buff is applied for Iron Banner. I am assuming that you can use it only once in the week. [u]The problem I have is, [b]unlike any other buff in Destiny, [/b]it's implemented upon purchase![/u] Know I love you Bungie but this is stupid! All the other buffs in the game require you to implement it from your menu. This is the first one that is activated directly from purchase. I'm sorry but you cannot just implement a new buff without explaining how it works, especially one this important. It just leads to confusion and people being angry.
