Clash of Clans

Why is it called clash of clans yet we can't have clan vs clan attacks like really what is up with SC

Alliteration makes for easier memorization.

Hopefully clan wars is coming soon

They need to think of a way to implement clan wars.

It needs to be more unique compared to what other games do so that it is more fun.

I'm hoping that it would be like some kind of troops vs troops.
But who knows?
