Just wait until you get to FE10, its the perfect blend of their chemistry along with Radiant Dawn supplying its own nonsense with things like its cutscenes and certain chapters. Its still my favorite LP on the channel.
I've watched them before when they were first posted but it's been long enough for it to essentially be a "new" experience.
In the FE11 videos the two of them made a few jokes about Mekkah eventually making a "Mangs Exposed" video, so maybe on some level they knew this would not last. Truly prophetic.
Currently I am playing FE11 myself as I was always a fan of it, I was a big fan of the H5 difficulty but it's difficulty was incredibly frontloaded.
And I have found a solution for this problem and that is the full content patch found
here.
This patch enables you to play the prologue on every difficulty and it's just amazing in my eyes.
Those few prologue chapters allow you to level Marth up sufficiently where he can actually be a valuable unit I found.
Instead of a level 1 shit guy you will have a level 5-7 Lord with acceptable stats who may also double attack the incredibly tanky enemies.
This experience, playing H5 with a prologue, it made me think that maybe H5 was designed with the prologue exp in mind because in this playthrough I was actually able to fight the enemies on somewhat even footing.
If you have the urge to play FE11 again on a high difficulty I strongly suggest you use this patch.
This patch also does a few other things which are optional, I have enabled all of them.
You can enable gaiden chapters to be automatically accessible so you have even more exp and some rarely used characters to play around with.
Furthermore you can enable FE12 reclass options, meaning you can have Female Cavaliers and Generals (though no mixed sets for males).
I'll post a few of my noteworthy units, I am on Chapter 11.
First is a Unit I always wanted to use but she never made the cut


I gave her an Angelic Robe and she is reasonably tanky because of it but other than that she doesn't really do much for the army. I forged her Wo Dao to have a ton of crit and it took most of my money.


This motherfucker just kept levelling speed and magic so I decided to keep him around, he is surprisingly solid as a chipper and I might bring him all the way.

Cord...I really wanted to use him as a mage this time since I liked his speed but even while in Dark Mage he kept levelling strength instead of magic. I had to forge him a tome in order for him to keep up.
Maybe I should've just kept him in a physical class. At least he wont be weighed down by any tome.

Barst is an absolute beast, I reclassed him to Mercenary so he could level strength some more and to build sword rank for his Hero Promotion. All he needs was a forged Iron Sword and he is almost onerounding H5 enemies.

Thanks to the patch you also always recruit Norne and I was pleasantly surprised.
Archers are still very valuable and she got strength and speed blessed for me.
I forged her a Longbow so her 5 mov is less of a hindrance, very solid and fun unit.
Shiida as per usual is always amazing, her being able to reclass to Cavalier helps her tremendously, she still capped her speed and gained a bunch of def to boot.
I do abstain from just cheesing the game with her Win Spear too much though.

Holy fuck, that's all I have to say.
This guy is a fucking monster and can take on an entire enemy phase on his own, he is hard carrying me.
And finally Marth, he has been incredibly solid as you can see. His Rapier is almost broken and his crit rate with the Killing Edge is really good too.
All Marth needed to function on H5 was the prologue, a true shame
Furthermore I am of course using Jagen, Wendel and Lena but everyone already knows what they're like since their stats barely matter.
I am also not using Sedgar or Wolf since they kind of trivialize the game and aren't really that fun to use.
I tried to use Hardin too but he died and I wasn't gonna restart for him
