Gaming Golden Sun DD: Can get get all classes/summons with 1 Djinni missing?

[Fel]

I'm missing 1 water Djinni and can't get it, will I be able to get all classes and summons in the game?

If not, what will I miss out on?

If you miss a djinni from the beginning of the game, you cant ever get it!

Unless.. you cheat,

Use walk through wall to go back and get all djinni and summon

or just use a cheat to unlock them all.

No, you won't miss any classes/summons.
For classes you just need to start swapping your djinn in your party.
As far as summons go, you just need to get the summon tablet hidden trough out the Weyard. I think there are some summon tablets that are permanetly missable tough, but that's pretty early in the game, so you won't be missing much...
