Everyone except, Merlinus, Lugh, Wendy, and Bors are used. I alternate between lots of characters between levels. I also have no seal at the moment. I've had two Knights Crests, one used for Barth and another for Alan. I've also used my guilding ring on Lilina at Level 19

Using a ton of units just makes the game harder for yourself.
That's all I'll tell ya.

Maybe focus on a team of 12? I'm an FE8 player, so I try to hit the cap with a solid army of 10-11 people each with A Support with each other. Try to get a good mix of people in: don't use the same class all the time.

Try 6-8 or so combat units that you raise.
Every other one is a prepremote.

Then put in a stave user or two.
That's about 10 units for every chapter.

Let's see on my HM playthrough:
Dieck
Rutger
Gonzales
Allen
Lance
Miledy
Clarine

And I'm using a lot of filler units, Percival and Echidna are amazing.

For the sake of discussion, how many of you used the Jeigan on your first playthrough? Oifeys count as well.

My answer(only played FE8):
Did not use Seth.

inb4should'veusedSeth, Marcus, etc.

On my first play-through with FE6, 7, and 8, I never knew how strong and useful they were until I beat the game.

I knew Seth was powerful, but I didn't want to use him after I found that my other units needed experience. I stopped using him until CC(Creature Campaign), but not before some Valni.

It's time to give the infamous Tear Ring Saga a try

FE on the PS1? Do tell . I'll play it then give my final thoughts in comparison to the FE series. But looking at it, it's pretty much a new SNES FE, I'm game.

Well, I've arrived at the infamous Chapter 21. As soon as I barely survive one wave of Wyvern Riders and Paladins, 10 more take their place.

See?
This is why you don't spread your units out so much , anyways, Percival can take down many units and base Echidna/Bartre are great fillers for this chapter.

Rutger/Dieck/whoever is your bosser killer works really well for this chapter if you want the Gaiden (Protip: You want the Gaiden).
I find it funny, people say using you Jeigan ruins chances for other units to grow, but using so many units ruins their chances in itself...
I'll just keep soloing with Seth...

Which is why you focus on a core group of 5.

Eg:
FE8:
Ephraim
Natasha
Tana
Joshua
Franz.

Then build from there to fill the supports.

What.I talked to Miledy to get Gale but But the next turn he's still there attacking me? Whatever Lilina and Forblaze work wonders on Wyvern Lords and Mamkutes.

Yeah, you can't recruit Gale

Nothing too surprising anyways.
Don't waste Forblaze users BTW, it needs to be in tact for a little while, same goes for all holy weapons.

Here's a cool thing though: Gale has growth rates, so he was originally meant to be playable.

Clap Clap.
Congrats, you went to Serenes! GG bro.

Anyways, it feels better this way, Blazing Sword is already terribly written, so we might as well as get something kinda tragic, it's a nice change of pace considering how awful the story is.
