You should visit the Division forums. The game is just over 2 weeks old and people are already claiming that their friends have left the game, they have no one to play with, there's no content and the little content there is isnt playable for people who dont have friends around etc. Now, you could argue that the DZ is down to personal prefernces and that it's possible to work around the friend problem but what's absolutely a fact is that the game is full of bugs. Matchmaking is just a disaster, with people not transfering correctly, constantly falling through the map when zoning in, random mission zoning, missions not activating so that you have to leave group and restart the whole process etc etc. The point is; While the Division might have caught the attention of a good deal of players at the moment it's not the main reason Destiny activity has gone down. The activity in this game is nothing but a reflection of this game's current state, which is poor. People were basically pushed toward the competition, whether they were that interested in it or not (like me, I had no great interest in the Division but it's currently filling a void). The Division will have no longterm impact on my Destiny activity but I'm worried that my absensce in itself will. Hell, regardless of the Division I probably wouldnt have played Destiny atm - nor am I interested in a tweaked variant of a game mode I didnt play when it was first released.
