Thanks for all the feedback on Frozen Orb. There are some pretty significant changes coming next build that should address this (edit: as those of you watching the Q&A stream with Watcher are hearing about just this moment, as it turns out). In particular, Frozen Orb will return to the role that it had in Warlords: a 60-second cooldown that you use for AoE or for a burst of Fingers procs, not a spell prompted by a rotational proc. We are adding a new single-target spell to fill the rotational role of interacting with the Brain Freeze proc.

Note that the wording of Ice Floes was recently changed to specify "cast time less than 10 seconds", to clarify that it's not intended to work with Ray of Frost. The gameplay of Ray of Frost is that it's a ramping damage burst that rewards you for anticipating when you can remain still for 10 seconds (or at least, 8 or 9 out of the next 10 seconds).
