I do quite like the story behind the event, and I will say that a base attack isnt too bad if it has a story like this, however there is a great deal wrong. First off its very complex and if one thing goes wrong, the entire thing will fall apart, which isnt good for an event. Along with this, you are pratically telling the Battalion how to lead, which is a big red flag. Also the HP is FAR too high for the ECs. My suggestion is cut the HP by 1000 and have atleast 3-4 more ECs. For a base attack 6-8 ECs is a perfect number.
