So, I've been following this little argument, and I think I found the proper statement that will support the stance of keeping everyone the same height:

Seriously, if all the matoran are to be short-legged, how on earth do you explain the hunchback Onua-Axel hybrid figure?
I'm not advocating to make him the same size in the minifig form, but I'm just saying going straight from short-legs to special mold, and skipping the next height entirely is pretty strange. It would make more sense, I think, if the matoran were the same size as the toa, so that there would be no real dramatic change with the Axel-fig.
BUT that still leaves the problem of explaining why Onua increased in size when the other toa didn't. The solution? - Axel-figs make no sense.
The power the toa recieve is elemental energy. Not height upgrades.
Making them all the same height would, I think, make sense naturally. After all, the matoran are receiving ELEMENTAL energy to become toa. How on earth does this power after height? In G1 it was never explained, and it doesn't make sense either way. Plus, as it's been stated before, toa and matoran, in this G3, are the same species, and members' of a species are only different heights by age, not strength, power, etc.
Lastly, assuming that sets will include members of the government (AKA- Turaga), how would you differentiate them, as well? The only remaining options are woody legs or the HF mini-fig legs. You could give them capes, or armor, or something, the the toa will also have that now/in the future.
Considering the fact that, again, they are all the same species, so it wouldn't really make sense to make this group taller/shorter than the rest, the only real option would be to do something with aesthetics (AKA: Have really fancy prints, probably with gold/silver)
Short legs=No prints:
There have been no short legs with prints on them. They've gotten double molding, but no prints, which would make them look as though they're missing something, even if their overall prints weren't de-specialized/dumbed down.
In short, here's my solution:Yes my digital art skills are this bad.
Here we have the Ta-region's king (named Vohon an actual ta-matoran from G1; Vohon would but heads with Tahu, a subject/soldier, as they are both hot-headed and don't rationalize when they need to. The queen, Maglya (antother G1 matoran), is more understanding and is a person more fit to rule than he.
) , Jaller (Yes, I made the character a she), and Tahu.
Besides the fact that Jaller is a bright yellow, Tahu kind of sticks out more due to the blue prints all over him. Regular Ta-Matoran could have just orange or red prints, and the King would have silver, or dark gold or something.
