Do we have to play on the ladder?

[Ignatz]

If you haven't seen it yet:

Jah Jah Jah Bling

and

Cham

A interesting high level rune recipe. But it works only on open and ladder play.

So my question is this: Is Blizzard saying, with all these 'ladder only' extras "If you want to play legit, you must play on the ladder?" Or put another way, "If you want these goodies, you have to play legit?"

I didn't really want to play on the ladder, but now I'm starting to feel like that's the only way to go...what do you all think?
