Heh - still lurking. I go on Destiny each week for about 5 minutes to get my Variks package with each character and that's it. I'm really leaning towards not getting TTK. It is exactly as I feared it would go - once I took a break, I found no compelling reason to go back. And I really think things are much better this way. I was letting Destiny control my time with all it's daily/weekly/weekend (Trials) time limited bullshit. At first I liked the game for having that stuff as it gave you incentive to be on regularly. But now that I haven't been doing that stuff, I realize it was a huge waste of time. I was spending so much time trying to get groups together for various things or having to mess with LFG nonsense, that it stopped being fun. Trials was the final nail in the coffin for what was becoming a grind at that point anyway. The game simply stopped being FUN.
I still have the CE preordered at GS and I have some Xbox Live money that is expiring in a week or two. I'm not sure what to do with that since there isn't anything I want to buy on the Xbox One at this point. If TTK was up there for preorder I might do that just to use the money I will otherwise lose. But I looked last night and it appears that only the digital CE for $79.99 is available for preorder. If I thought I could portion out the physical CE contents (selling the base game and TDB/HoW code) and get most of my money back I'd do that. But I think the original game disc will be worth very little and the TDB/HoW code will be pretty worthless too as most people will just come in right with TTK. So most likely I'll pick up the GS preorder, stare at it for a few days, then return it.
I may wait till TTK by itself is on sale later in the year and grab it then. I have too much time into the game to abandon it completely. I'm also still toying with the idea of getting the PS4 bundle and starting over there. If I can get a good deal on the bundle at the last minute (as I see nothing now to indicate there will be one) I might do that.
TL

R version: I don't know what I'm going to do and will play it by ear as to cost/value whether I get TTK, the full physical CE, or even the PS4 bundle - or skip it entirely.
