Just remember that reclassing is going to be different in If. You can reclass characters, yes, but if I remember correctly, you can only reclass your units a limitied amount of times with that new Parallel Seal, that seems to be the Second Seal replacement.
I'm not too sure if Gale Force is making a return, they are balancing abilities by the looks of it and, as you said, Gale Force is too OP, specially with already reclassed units.
Like abilities, weapons are getting re-balanced. While there's infinite weapon usage now like in Gaiden, there will be certain advantages when using Iron over Steel or vice versa.
This is me right now too, if you haven't guessed.
