Its all hindering terrain. Breaking this rule makes all sorts of ridiculous crazypossible. Breaking this rule makes wizards ridiculously overpowered.
CS is wrong.
So are you saying that if a saving throw isn't allowed, people will suddenly rush to play wizards who otherwise wouldn't?

In my experience, Wizards have been the "cleric" of 4th edition: A class that a group probably should have one of, but it seems NO ONE wants to play one. I suspect it's because some DMs aren't using minions often enough, but it's true. I had to give the Wizard player in our game a few perks (like allowing him to cast his dailies and utilities like a 3e sorcerer, basically) so that he didn't quit in frustration.
That said, it's correct -- hindering terrain of ANY sort should get a save.
