*Opinion Time* Is Legendary Lyn's Map the Hardest in the game?

It was about average difficulty for me using flier emblem.

Try using a horse emblem, as it makes life much easier with the great mobility. I got to admit, it is a very annoying map, however if you play it smartly, it can be won easily. I won it by engaging hard before too many people get summoned.

Since you haven't tried the Fallen Takumi and Valter map yet, I would say your opinion is 100% valid and that's ok.

I personally don't think anything will top Fallen Takumi though.

I did it with Rein, B!Lyn and 2 dancers on the first try...
Fallen Takumi was the hardest for me so far and the Legendary Robin one wasn't easy as well.
Just use reposition etc. and it shouldn't be a problem

I did it with Like (qr swordbreaker) and fliers. He can take care of the bows and swords and they guidance him and pick off units

Not terribly diffcult, just needed Grima to tank with Ward and Fortfy the Bridge, along with BK killing the Hammer flier, Hector(LA) tanking a few, and Tharja(W) buffing.
Harder than Valter(Not by much, tho) and not nearly as hard as Fallen Taco.

I'm using a flier team and Fallen Takumi for me is the hardest as the terrain offers almost no advantage to fliers (I believe there are 2 squares only fliers can access). You also have to deal with 2 Dazzling Debuffers, breakable blocks, Skadi lazer and reinforcements ready to pincer your team.

Then again, my team situation was different back then, I was using an all melee flier team (no dancers, DC or Galeforce). Now, I have F!Grima and Spring Camilla to deal with archers. Maybe I'll try an all-melee team against Lyn's map before it ends to see. But just by looking at the terrain and enemies that appear (as well as their spawn points), it's not as tight. Risk of being overwhelmed is low unless you decide to stand and fight in the center by bridge all day.
