I loved the flaming head but as for the nightfall modifier I don't see the need everyone is saying the night drops are horrible but at this point they are the exact same as HoW. Legendaries drop 5 below max light (if you are 330+) I don't remember the exact number but I think it was 335 and you had to use etheric light to get it up to 365 same concept. For the boost for faction/Vangaurd you used to be able to rank either or now it is both, plus there are class items to provide the same boost the nightfall granted i believe if not more. For the XP boost we never used to be able to use motes of light to level gear and gear takes way less than it used to to level. All that being said mechanics wise I can see them not needing to re-add them nostalgic wise heck yes I want that back I used to get up at reset to save Exotic chest checkpoint on VoG and run the nightfalls before work I miss that.
