@T0rin:
What ilevel is your gear? (if you're around 85-90 then it'd be within the range mentioned earlier with the +10 from 64).

I just went to coerthas and started hitting the left side dummies, no contagion casts there either (was in MD killing gigas, lightnings, snakes). If I drop a bio 1 on it then it casts a few seconds (between 1-3 wind blades).
Anyone else have agro on it maybe? (Also, was shockwave casting at all?)

As for stopping casting, I just bind to g (sic) and shift +g (obey), if I need to run to dodge, sprint(f)[makes me laugh every time I type it] and pet obey are within the same hand gesture. The timing doesn't have to line up 100% (15 sec is 15 sec regardless of if the dot is at 3 seconds or full cast) as long as all the dots are on it (at least in my mind).

Time to load up that parser maybe it can reveal something I'm not seeing regarding obey vs sic.
