I want to place one Earthshaker battery as well as Command Squad and Tigurius on the Skyshield while the other battery will be somewhere nearby (out of
LOS if possible). Tigurius will roll heavily on Divination to support artillery shooting. Sabres will provide Intercept and
AA-shooting, Platoon should bubble-wrap Skyshield and Earthshakers. Platoon Command Squad and Veterans will ride in Vendettas for late-game scoring and to create pressure in the enemies backfield. Hammenators will either serve as
CC-protection or Deep Strike to the enemy line if neccesary (Teleport Homer in Scouts will help here). Tacticals will do the same. Ratlings... well, I had 30 pts and decided to take them because they are funny

. And of course they can always infiltrate some good-placed ruin and serve as distraction for enemy units or even get Linebreaker if they will not be killed.
Whats your opinion? Is this list as good and balanced as I want it to be?
