Skratti and Vanjarl arent summoned. They are national commanders, who can kill decent armies with equipment. Please, name a summoned thug who can do the same for ~25 gems, including item cost.
Now, _something_ for Caelum doesnt have to be _that_ powerful. By the way, please tell me how would you outfit a banelord to fight Shishi. Because Shishi, you see, can kill both banelord and mortal armies without changing gear. As a harder task, please try to outfit a Raksharaja or Dakini to fight Shishi.
Death only has ony really really great SC chassis, afaik, and that's tartarians. So I kinda agree that its a good idea to give other endgame chassises. But Shishi isnt an endgame summon, its a mid-game summon. And Death has nothing comparable, not even remotely, because Bane lords will be eaten by Shishis. Literally.
Ah anyway. I can adjust to this mod, not a problem - taking a God with A4 is ok. Just... take a look at them, how they perform in the games to come. I have a feeling Shishi will be a wunderwaffe; employ them or lose to them.
