On the warbeats i just figured that the healing warbeat is pretty bad, especially without the cabbage. So i just prefer to have more options to where i send the plus to hit.
Shaman is running the 2 plus to cast, not the double cast. Casting hand of gork on a 6up isnt as reliable as i would like so i opted for a 5 up instead.
I'm still trying to work the unit sizes. Could do 15,10,5 on the arboys and 9,6 on the Gore Gruntas.
Another option is to run the doublecast on the shaman, and run 5 ardboys less and play geminids instead.
But i will do some more play testing with this list and figure out what adjustments i would like to do.
