This is interesting, very interesting. I'm sure the Change Proofs will be available in unlimited quantities during the postgame, and I hope it's the case. It'd be more interesting than maxing stats through stat boosters, certainly.
For the main game, I'm guessing they'll be limited well enough, especially early in the game; more will probably show up later, and by that point drastic changes won't be so easy. Secret Shops will likely be like those in FE11/12 and offer the Change Proofs, but in limited quantities. It'll probably be possible to get more Change Proofs when desired from merchant characters and the like by doing side stuff with the world map, but for a straightforward playthrough, it should all be managed well enough that I won't feel any qualms about using them, which is good because the level-reset will come in handy even if nothing else will. The level-reset is also more reason for the game to not simply hand them out.
This probably explains Sol's stats when promoting: he used a Change Proof but stayed as a Cavalier, just resetting his level, so when he leveled up more, his stats got far beyond what they normally would be for an unpromoted character. Chances are, characters with fixed classes will have the same option to use it that way.
This expanded class changing system also seems to confirm that my theory about growths continuing to change with differing classes is correct, which is a great bonus for the class system even when left with just the basic branching classes. Speaking of branching classes, I wonder how this will fit together with them. Branched promotions will result in a very large pool of classes, so it raises questions about how the groups will be set up. Perhaps the class sets will include things like the Cavalier/Knight family, the Pegasus Knight family, and maybe a couple of other things: the sets start out small, but will grow after promotion when more options are available. (Cavalier/Knight/Pegasus Knight --> Paladin/Great Knight/General/Falcon Knight/Black Pegasus). Or perhaps it will be more irregular, resulting in characters maybe getting a different set of options if they promote or if they switch to a different class before promoting. All very interesting.
How about a line of generals all using defense cry on each other? As long as there's no magic user it's invincible. :P Except they seem to be mixing weapons and magic all over the place, so that's probably a no go.
Only if the bonuses stack.
I like the presence of Defense Cry; it indicates that they're going for a more varied FE9-style of masteries that can actually give different classes different results, except they seem to be actually making those masteries actually good and relevant.
