Yeah, seriously.
I am a big fan of a lot (actually all) of the changes brought over from the echoes and expanded in 3H.
Especially the fact that we aren't stuck in 1-2 range anymore, which seriously fucked Archers over in almost every other game.
I never grinded, didn't recruit from other houses, only did Story + paralogues, hence 3H was actually quite challenging. No map made me want to kill myself either except for Bernie/Petra paralogue. Many other FE have more maps that make me wanna drop the whole series altogether.
Many of the maps had secondary objectives you could complete, which made me split up my army. There's also the fact that the game has a heavy player phase focus, since enemy units are very strong (and i am not talking maddening here, but hard), but def stats all around are pretty low. I enjoy Player phase focus much more than enemy phase focus. Majority of the series sadly focuses more on enemy phase.
