Two of the powers are incredibly useful in PK, and give huge bonuses to fighting battleragers and other mages - things mages tend to have the toughest time with at hero. (The other two CAN be useful in PK situationally.)

That's a pretty good deal for what essentially amounts to zero obligation to do anything but be interesting and weaken the Veil, which mages ought to be doing anyway.

Yes, more powers were planned. However, for a number of reasons, it would just be best to just accept the current set of powers as the only powers you're going to get.
