I tried doing a search for fleet footed before posting this, because I feel like it would've been discussed in a million threads if it were slated to go away, but I didn't see anything else about it on the forums.
Did the baseline fleet footed passive (15% movement speed) get removed in the beta? I was looking at the beta talent calculator, and I didn't see it available for any spec. Link below.

(If you go to the Live calculator, you can see it as a baseline ability)
