So I played the fan translation of Nohr and am currently playing IK. Nohr is really fucking good. Played Hard Classic and it kicked my face in a few times, especially near the end of the game. The story is pants on head retarded but the gameplay is extremely solid. Every map having a gimmick through Dragon Vein, terrain, or failure states made me feel like I was playing an actual Fire Emblem game again. The lack of grinding is an obvious plus for how it restricted resources and forced the designers to actually think about the level curve and scaling of the maps. I never felt like I lost a unit because the game screwed me over, it was always because I misplayed. The changes to the pair up system are great, splitting offensive and defensive pair up made it something I had to actually think about instead of fielding 10 units and having five of them become pair up fodder.
Unfortunately I'd say the split paths had many downsides that kept the game from feeling complete. Half of the classes being enemy only felt unnecessarily restrictive. The only good dodgetank I ended up having was my OC donutsteel as a Trueblade. This ended up being harmful in later chapters since in Nohr the AI ignores enemies they can't damage. So since the units you get in Nohr are all either tanks (Great Knight is fantastic) or delicate flowers with not enough evasion there's very little chance of having a real dodgetank unless you choose Samurai as your alternate class on a whim. This is also made worse due to the fact that the unit choice isn't very good. On hard mode the list of viable units post-midgame is hilariously tiny. It's essentially OC, Marx who is essentially FE10 Haar, Camilla (who falls off endgame), Leon, Aqua (dancer utility is fantastic), Elise (staves are amazing), Benoit, and maybe Cyrus if you get lucky with some speed growth and have a good pairing attached to him. Notice how this list is mostly dudes and siblings. The female units and non-royals in general in Nohr are all terrible, meaning you're probably carting them around later into the game than you really want to so they'll pop out a kid. Thankfully the children come with master seals that also level them up to a chapter appropriate level to avoid having them all be Ests, but actually getting those children is a matter of bringing sub-optimal units into chapters they don't belong in to get a somewhat decent unit out of it. I ended up getting four children: Aqua!Kanna, OC!Shigure, Camilla!Ignis, Effie!Sophie, and Elise!Ophelia. These are all optimal pairings and the children all ended up being dead weight, rally bots, or support. Kanna was immediately benched since Dragonstones are ass and Aqua killed her defense base. Shigure ended up being a rallybot and debuffer with Draconic Curse. I made Ignis a Berserker which was pretty fun but extremely ineffective endgame since Benoit gives him essentially zero speed growth so I had to slap Competitive on him to avoid being doubled. He had 60+ crit on every enemy in endgame though and since killer weps now make crits do x4 instead of x3 he was a pretty decent luck based attacker. I mainly chose Berserker since I didn't need another fucking Great Knight. Sophie was pretty great at first but her lack of supports bit her in the ass since she never had a chance to grow. It's kind of funny, I only brought Odin along to finish supporting Elise to pop out a kid to use Elise's incredible genes, but Ophelia ended up being kind of shit. Couldn't hit a damn thing and her crit wasn't high enough to make use of her personal ability so I ended up just using her as a support unit. So while they seemed to be useful, even with optimal pairings the kids turned out mediocre thanks to a lack of supports. They were more trouble than they were worth. Of course this isn't even speaking of the horrible excuse for children in Fates. Where Awakening shoved children in through time travel, Fates used hyperbolic time chambers as probably the dumbest plot device I've ever seen. Though considering how terrible the rest of the plot was this was par for the course.
Hopefully IS uses Nohr as the standard moving forward, though I highly doubt they will. Idiots with shit taste review bombed the game in Japan since it was too different than their beloved Awakening. I'm expecting the same thing to happen in the West as we all know how terrible reviewers' tastes are. I'd rank Nohr up there with FE7 and Heroes of Light and Shadow. Not quite as good as FE5/9/10 but certainly better than average. I can't speak much on IK as I'm only on chapter 12 Lunatic.
