I hope I am on time for the upcoming update.
I heard from several players that the tsr raid feels unbalanced. From experience I know that every tsr slows down tremendously when p3 starts. In my opinion the difficulty does not cause this, I wil elaborate below.
P2 and P3 have equal drop rates (own experience), however in p2 I can close my eyes and easily score 4500 rpp. p3 requires attention, health pots and haste pots to only get 3000 rpp. This results is worse drops for p3 when compared to p2, while the phase is much harder.
My suggestion is to make sure p3 pays double of p2 to boost attendance for p3. I would be okay if p2 was lowered to Sq p3 drop rate if double of the current drop rate would be too high.
