The way it's implemented makes it impossible to make an informed decision unless you've actually had that form with a previous character. Unless "informed decision" means someone else's opinion on the forum. But, how many shifters do you think you'd have to play before you got to play every form in a single foci?

That's another reason I think switching should be cheap. I've had three shifters get a certain top tier form and it's very frustrating if you're trying to experience something new in a certain foci.

But, the funniest part is that you get the highlighted notice that "You are no longer able to change forms!" RIGHT AFTER you shift into your final form.

I mean, either:
A) They already know this so the message is not needed, or
B) They did not know, and you've decided to wait until the knowledge is no longer useful to point it out.
