If they aren't changing the droprates for anyone, it's even more unlikely that they would for a specific group. It goes against SE's philosophy of allowing newer players to catch up. What took weeks or even months to complete like coil can now easily be completed by a fresh 50 in a couple of days. This game is operating on the model of throwaway content. As endgame gets further away from the point of a fresh 50, the things required to be done to reach the current endgame will be made easier. For those who finish content early, that in itself is the reward. There has been no indication that this trend will change from what SE has been doing so far.
