I might be wrong about personal Force Field now that I look at it. There is that last line:
"Specific power instances were altered to eliminate duplication of powers."
Linkerated, for your convenience

Awesome! Thanks!
Am I dreaming?
Here it is in the extended patch notes:
Ancillary/Patron Powers
Ancillary Power Pools are now available to all characters that reach Level 41, regardless of Hero or Villain status.
Once a Patron Pool has been unlocked as a Villain, it remains unlocked even if you later switch sides.
Patron and Ancillary equivalencies are as follows:
Scrappers get Stalker Patron Powers, and vice versa.
Tankers get Brute Patron Powers, and vice versa
Blasters get Mastermind Patron Powers, and vice versa
Defenders get Corruptor Patron Powers, and vice versa
Controllers get Dominator Patron Powers, and vice versa
Specific power instances were altered to eliminate duplication of powers.
So now every MM can get personal force field (via Force Mastery), not just ones who take /FF. Or go with FlameMastery as your ancillary, and get Rise of the Phoenix, or Cold Mastery and get Hibernate. I wonder how long it will last before they start to change it?
