E) It's a similar mechanic used by and, and it's approximately 1000-1200 from the center of the AOE. Also, disruption is any form of CC that cancels channeling: which is everything except Snare, Blind and Slow (silence, stun and suppression, but also others).

R) The effect is that she channels for 2 seconds and then transforms her target (similar to ). If person B disrupts Yaga while she's channelling, person B will become a frog for the full duration instead of target A (Yaga stops channelling: she was disrupted).

I hope that clears things up. :)
