Currently on Chapter 5 of BE, first 2 chapters were difficult cause only Edel and Byleth could avoid getting ORKO'd and hit rates are so low. With BE your damage output it pretty low early so you need every hit to hit otherwise you get fucked. I've had to rely on 50-70 hit rate gambits hitting once or twice to deal with the 13 AS enemies charging at you in chapter 2. Chapter 3 and 4 were surprisingly really tame with enemy AS being in the 5-9 range outside of a few rather than 9-13. Enemies overall haven't scaled up much from chapter 2. My level ups have been absolute trash though so my Ferd, Caspar, and Petra all still get ORKO'd (With the added fun of both Petra and Ferd getting one speed and strength in 6 levels). Dorothea is still a bitch to train and has fallen behind pretty hard, thankfully Lindhardt and Hubert got to level 5 in chapter 4 so they can be used more now. I imagine the spike around chapter 12 will be pretty brutal.
