Morrus said:Thus people claiming that "saving throws" are now a 50/50 coin toss are drawing the wrong conclusion mainly, to my eyes, based on the fact that WotC used the word "save". In my opinion, they should have used an entirely new word.
While I agree that the problem is that people are not understanding how the system works because they are making assumptions about it. (Anyone who was listening when WotC said "saving throws are still in, but they aren't the same thing they used to be"" knows to look at how it's changed roles.)
I don't think they chose the wrong word for it though.
Defenses - your ability to protect yourself from a harmful effect. If you're more defensive, you're more able to protect yourself from being effected from that harmful effect at all.
Saves - Your chance to "save" yourself from the ongoing harmful effects that you were subject to. You're trying to save yourself.
If anything I think the terminology better describes the function rather than worse. It's like martial powers being called exploits. After the initial off the wall, gut reaction "what are they crazy?" complaints, those that actually learn what the words mean, will note that the terminology is actually very descriptive of the action being done.
