I haven't pre-ordered TTK, though I will more than likely buy it on release, and still enjoy playing Destiny (though I do play it less than I used to). I haven't really bother watching the streams or reading all the hype as I'll find out what TTK has in store for me either on release or when/if I buy it. The lack of any form of in-game optional MM/LFG for end game content is the main reason why my interest is waning as I'm fed up of paying for content and not being able to access it unless I'm prepared to go through the unneeded rigmarole of leaving the game to go to a website to then have to wait for 5-30 minutes to find people before I'm actually able to play. At no point when I have LFG'd, and finished the content, have I ever thought afterwards "that would've been impossible via MM" and I'm getting tired of not just being able to play whatever content I want, whenever I want without having to waste time finding people to play with.
