Flaws in Spanish

My Spanish teacher insists that Spanish is the greatest language and that there are no flaws in it, when in fact I know all non-constructed languages have some flaw in them.

I need some ammo to fight back, and then it can continue into a discussion I suppose.

"paleta de malvaviscos cubierta de chocolate"

vs.

"cocolate-covered marshmallows"

any language that uses 6 words where another language can use 2 is inefficient.

3 if you don't count a hyphenated word as one. it's still half.
