I don't think you should be able to instantly switch anywhere though, you should have to go back to camp. I didn't like that feature in KotOR and Jade Empire either.
And DA isn't anywhere near 95% combat zone.
I disagree, on normal you can only switch in non combat zones to, in that zones you can also leave for the camp if you want. So if ther was not an instans switch option, one would waste long time in front of the load screen, just to switch players! I do like the load screen.. but not that much...
