I so far see no issues with the game.
I don't have much time in world (~400 hours, which is small compared to most serious players), but I can already say Rise is 1) more accessible to new players due to the tutorial and low rank not dragging on. 2) More fair, as hunts start getting harder a lot faster in world, but you have plenty of time and resources to make the transition to high rank less painful. Finally, 3) still monster hunter. I feel many players were worried that this game wouldn't feel like monster hunter, but that's not the case. Weapons retain and gain so many new features that the game feels fresh yet familiar.
