Full Support 20/20

[Matthias]

I'm really proud of this one. I took twelve characters, got nearly all of them to 20/20 (couldn't get one for obvious reasons, and Florina was two levels short... because she couldn't go on the last mission...). Here they are (without stats, because that would take forever)

Hector=Florina-Ninian=Eliwood-Lyn=Kent-Fiora=Sain-Priscilla=Erk-Serra=Matthew -

Why do you have only one primary axeuser?

[Kenshin]

That one axe user is a tank. Why do you need more if you've got that tank to back you up?

[Alan]

Because one unit can't get to all lancemen and at the chapter where you fight Erik and all the cavalry of the ones he was planning to train the only ones present where Hector, Eliwood and Erk I don't see how this lineup turned out most practical, that's all.

[Matthias]

Matthew and Serra were there as well, though they didn't help too much.
Seriously, you don't need axe-users in FE at all. Dorcas and Bartre aren't really good units (my opinion).
also, i was playing HNM, so it's not that difficult anyway...
