Come the middle of Feburary, I'm sure it will be much worse. As for me, with Monster Hunter less than 2 weeks away, I will most likely not be coming back until March.
It was frustrating finding a group to fight Crota this week because they filled so fast. Then out of the two times I did, people were giving up after about 5 tries, eventually causing a dissolve in less than 30 minutes.
I think Hard Crota was the last straw for many. It tops off the terrible experience TDB has been. The rewards weren't worth the headache either, weapons worse than VoG and an exotic that is probably the worst in the game.
They have to do something different for HoW, there's no way Destiny will get through the summer til September if they keep same messes uncleaned.
