what content has been removed ? all of the strikes are still there, playable at both their starter difficulty, and in a playlist
all of the story missions are there, as are all the launch crucible game modes like clash, control etc.. same with the crucible maps. They even get new ones for free here.
The only thing that's been removed is the weekly heroic strike, but that was removed for us all. What are you thinking of that's been removed ?
The nightfall is now light level based, and you can get to 280 light using all the vendor gear which vanilla players should be able to buy ?
All the vendor gear requires you to be level 40 which players who haven't bought TTK are stuck at 34. However the herioc strike, NF's etc. have done what they have in previous DLC's - the level which you can access them has increased inline with the new increased level cap. The difference is obviously, previously you onyl needed to be level 20 to equip legendary so could increase your level to the new cap even without the DLC. However now it is XP based it has moved NF's and herioc strike out reach of people who haven't bought TTK.
I know the arguement is that 'out of reach' is effectively the same as removed but I dont' know what people thought was going to happen.
