@Tahquitz: In CWs roadmap, he does allude to "Simulated attack powers" on target dummies.
"Target Milestone: Future, long term
Estimated Completion: Whenever
Simulated attack powers, possibly usable on target dummies
Handoff to realtime communication service for more demanding activities, such as PVP Arena matches"
This quote was taken from CWs roadmap. However, I wouldn't look for this in the near future.
