I noticed that yesterday. The damn Hobgoblins are using tactical insertions as soon as they spawn! I'll kill one, kill the other and the one I killed the first time is there again, and when I turn to look at him, guess who came back? That's right, the second one... Bungie acted like angry children on that hotfix "They already beat it, we're going to make it harder because that's unfair, they cheated!"
