The idea behind this AI is early aggression, countering everything opposing AIs might use and most importantly - dealing with current archer/skirm meta. Since I'm still a newbie I'm not able to develop a sophisticated eco/military script in a reasonable time. Instead early rushes feel like the way to go. The AI is still in development and I hope it'll be ready for Kimberly's tournament or at least able to show general idea behind it.
Expect flavour taunt messages (one day) as there's a whole book of them available
