I don't like auto-decrypting lengedary engrams. (Criticism)
It's weird. On paper, auto-decrypt sounds great. Why waste time going to the Tower if you don't have to, right?
Well, I don't like it. I could make an argument about how it turns inventory management into a hassle. Every time I get a new legendary drop, I feel like I have to stop and look at it, infuse, use it, or lose it. It encourages me to stop playing the game to look at the new thing I just got.
In reality, though, I just miss my end of the night tower run and dropping ten legendary engrams on Rahool at once. I liked my end-of-night routine, and auto-decrypt engrams screwed that up, and I don't like it.
