>>21609244I even like the idea, but it wasn't done well in design execution - too jarring of a sudden change. If Quilladin had started the shift it might have been great.
The other part where that design failed, I think, is that nobody needed an improvement to believe the shell was any harder. We never needed Blastoise's shell to change for its durability to be believable. Hell, look at Chespin's Pokedex entry:
"Such a thick shell of wood covers its head and back that even a direct hit from a truck wouldn't faze it."
