sorry guys.. but especially this fight here

shows that the battle algo is completely 100% BS!
If they want to keep it that way they need a waterfall where if a very powerful group just wiped out another group and has a lot of unused attack power in that strike left, the next unit group is attacked immediately with the remaining attack power.. this goes on until there is no remaining attack power...
who comes up with such a terrible idea???
I really don't get it...
and what about the range units? should they not have the first shoot?
