If you had the power to add one feature no questions asked, what would it be?

and for esunaga to be added to the game, maybe on like a big cooldown or something.

This would make the Puppets' Bunker trash mobs so much less aggravating...

But... Spell 1, 2, and 3 IS the classic, original style, I thought?

Yes and no. I think the original FF limited spell names to 4 characters; you had, like "FIRE" and "FIR2" and "FIR3", yes, but also Sleep was "SLEP", Temper was "TMPR", Lightning was "LIT", etc. So you could argue that "Fire", "Fire 2", "Fire 3" and so on were the classic, original style, but I feel like it was more "whatever we can fit in four characters that won't be TOO confusing."

And while FF2 introduced full spell names and appended numbers, it was a different thing; you had one "Fire" spell, and as you leveled it up, the damage increased. So "Fire 3" was not the same thing as Firaga, but rather just "Fire" with more damage than it had when you learned it. (Also, I think this maxed out at "Fire 16", so... let's just move onwards, so as not to give the Black Mages any ideas.)

I think it was FF3 that introduced the "Fire", "Fira", "Firaga", "Firaja", etc. naming scheme, but I might be wrong on this.
