I answer to your message here since it might me a more appropriate thread
Your comment picked my interest, and since I had my first terrorized cows this morning I made some testing and came to a different conclusion for cows
My setup before was more MF-oriented (using cham'ed shako and dual nagel in particular), and skill-wise I was using fade for resists, and the most damaging possible setup : fully-charged FoF, CoT, BoI, Tiger strike and PS charged with fire or lightning depending on the area
For cows I switched to the following : switched shako for faceted griffons, and nagels for raven frost + 10 fcr ring
I switched fade to BoS : then I can come back from Tristram to town, go to Akara, open cow portal and kill the first cows without loosing charges, + i reach a better ias breakpoint
Since I have a 10 fcr crafted amu, I can reach the 65 fcr breakpoint on main weapon, which is already faster than a javazon with 99 fcr, and I could even aim at 102 fcr on swap if i either used a 15 fcr amu or an extra 10 fcr ring. I did not try because I dont have the amu and cannot remove raven frost since i dont have a cham'ed griffon yet.
For the charges, I use PS with two charges of course to go for lighning damage, and the main difference here is that i dont use fist of fire because it converts all the physical damage to fire (if i understood well), making life leech and mana leech non existent. So instead I can use Cobra Strike and get insane life leech and mana leech.
With 3k+ life, Weapon block and Cobra Strike, fade seems to become unncessary. I have around 20- 40 to all res with my current setup and did not come even close to dying at p/8 terrorized cows. Of course i did a 1hour test only, so it needs to be confirmed on the long run.
With that setup it looks like I can run cows significantly faster that my javazon. I did not time my runs so I can not be more precise and it needs more testing of course
I personnaly did not have problems for picking stuff : I usually keep 2 full columns in my stash + cube so I have enough space to just pick everything I find and identify at the beginning of the next run. Of course it's space that could be used for more skillers, but this assassin really does not need the extra damage.
The 15s delay gives me enough time to manage picking items. Also It seems that herding is not necesary so item cluttering is not as problematic as for a javazon
So in the end my conclusion is that this build deserves some further testing on the cows level but my intuition is that it might actually beat the javazon. At least I found that the runs are more comfortable than with the javazon : no herding, faster teleport and no mana issue + you can kill easily the immuned bosses including the cow king
