I hate the loot box change. You're getting less rewards overall if only one feat is missing which is demoralizing and demotivating. You don't want to gear your toons anymore when you know from the start that you can't complete all of it. You don't get your rewards right after completing feats and have to wait for days. And last but not least it's another 'box', nobody likes boxes in this game as they always hide what you're getting. It gives you the feeling that your reward will be randomized like all the other boxes out there even if it's not true.
Whoever thought this would be a good idea deserves nothing less but a 'No-christmas-tree'-christmas this year.
