Was wondering if any information or knowledge of this subject exists, was not able to find anything concrete on whether said skills, and similar non WD skills, work on players like the would monsters?
Doubt it, unless it took control of the players character and I highly doubt that will happen. These skills will be useless, in PvP and probably in PvM just like before. Fun to toy with but in long run good players will drop them for more damaging skills.
Ah, hah, yeah. I'll admit I didn't watch all the arena videos. Without something like that it was seeming like a pretty uneven match with the barb's potential health regen countering the DoT, and a mild lack of reliable escape mechanisms ,seemingly only WoZ, GotD, and summons to bar passage. Actually, that might be enough now that I think about it. Still a wavy-hand thing though.
Curious after mulling over WD vs Barb situation.

They will work in arenas, though they may be subject to altered durations (for instance) than to their pvM counterparts.
