For me I only have the crucible/pvp to keep me busy as I've already done everything else. I'm not sure yet if I'll get TTK or not, but it's not my priority #1 come September (that belongs to MGS5). Add in the fact that like the op said most of my clan & friends just have stopped playing. I've been a beta player and even took a break in between TDB & HoW as I was getting burned out, add in the fact that they aren't always fixing things that are broken just to artificially extend the length of some stages/make them harder. For an impulse buy I've gotten my money out of the game I suppose.
