I actually enjoyed the monastery in 3H. The downtime between battles was enjoyable for me. I never found the maps unenjoyable, and I liked that there were a few that I personally hadn't seen anything like. My example being the canyon where you fight the giant beasts for the first time. Engage cutting all of that out in favor of trash characters and so far a lame plot really lowers its value in my eyes. If I had paid for this Id feel ripped off because this is a subpar product. Also comparing Engage to Fates is actually hilariously fitting. I didn't have much fun with Fates as a whole, and I likely won't ever go back to 3DS emblem outside of SoV.
I found the Monastery got tiring after my second playthrough and it just wasn't fun (especially once I started to check out of the story so the dialogue meant progressively less to me), and you have to mess with it a lot especially early on which made repeated playthroughs a chore.
The biggest problem for me with 3H's maps is that the very easy access to warp and stride make it easy for even casual players to storm the maps and rush the boss in a game with a lot of kill boss objectives and kill boss is a really abusable objective when most bosses aren't threatening and can get destroyed with ease. Save for the monster enemies blitzing down the bosses is pretty easy to do. This isn't even talking about the dancer battalions. I'm by no means an LTC'er and I stormed most the maps really fast with mount spam + utility mages for warp/physic.
Hard was a total joke too, like even easier then HHM from FE7 easy imo so if I wanted a challenge I had to deal with the sloggy Maddening early game that I just didn't find fun to deal with pass bandits, poison strike spam archers, ambush spawns from Sylvain's brother's chapter, and sketchy hit rates for the first handful of hours unless you spam combat arts. Conquest or even Radiant Dawn didn't make me hate the early game this much because they had early prepromotes to make it more bearable (especially if you went female Corrin for Paladin Jakob).
I haven't gotten that with Engage so far, but we'll see how it holds up as I already want to try a different playthrough with better foresight of how the game develops and what all the Emblems bring to the table. I think my biggest complaint right now is the bond rings are kind of a scam if you don't do the save exploit to make the whole mechanic feel like it is worth it.
I'd be curious to hear who you guy's MVPs right now are? For me its Yunaka, Merrin and Panette bar none:
Yunaka is S-Tier for the Pass skill alone + her absurd dodge tanking ability
Merrin is also an excellent dodge tank, but can actually put out some significant damage. She's an absolute monster paired with Alacrity and Speedtaker. Wolf Knight might easily be my favorite new class.
As for Panette, her raw damage is so goddamn high she can kill most things with a baby axe. Plus her high HP pool paired with all those skills that give her crit chance for every point of lost health makes her an absolute wrecking ball. I never thought in a million years IS would make an Axe user that's not absolute shit.
Louis was an easy MVP in early game, but his role has significantly diminished Mid/Late game due to his lack of mobility, terrible speed and chain happy enemies.
I chose not to lean into Yunaka super hard because she doesn't work as well on Maddening due to inflated stats making her tink and the AI avoids 0% hit rates so her dodge tank memeing isn't that consistent. She was okay but nothing fantastic, knifes are neat but I don't think any of the base knife users have the strength stats to make them worth it long term. +3 iron is cheap though and a worthwhile investment to make the early game easier and faster, but +5 silver feels too expensive for what you'll get.
She helped with bosses due to poison and she was a nice replacement with reasonable 1-2 range. Zelkov also kind of does her same job when he shows up unless you really abuse the first 9 chapters to make Yunaka stand out and Zelkov is free. Tiddy Zelkov/10
Merrin is fine, she's filler and free pretty much. Nothing amazing, but she'll do stuff when you first get her. Wolf Knight feels like a class you need to experiment with other higher strength characters to stand out as the base users don't quite have the stuff for it. Woof/5
Panette I'm trying to actually use because I can see the potential she has, but I'm not very happy with her low BLD and okay SPD when she uses axes, she feels like she needs Ike's bulk enabling to be truly amazing because otherwise she just single hits someone for a good bunch of damage unless she crits as opposed to killing them and she doesn't quite have the bulk to make me feel safe throwing her to crit a bunch of people. Her join chapter also had a good handful of swords so I couldn't use her as freely as I'd like. She is still a free unit and is probably better then someone I was using earlier so I'm fine with her. Needs Ike/10
For me it is Chloe and Diamant as my biggest play makers. Chloe is Florina with better starting bulk, you slam all your stat boosters on her and she snowballs while Louis backs her up and becomes your first real Wyvern. Early fliers always have potential in Fire Emblem. Diamant is a fucking beast who does just about everything, great bases when he joins, good class skill, throws hand axe good. Louis I had a feeling would fall off without Sigurd and I was right so I've pretty much benched him now but obviously he was good for the early game.
