A list of counters seems nice to have for me as newby. I dont really understand the overview. Can you explain everything a bit more?
I think some of the numbers on the overview chart are not quite correct (for example, the bonus damage mamelukes take from halbs, the one that CA take from skirms or the one that turtle ships take from towers) - I recommend you look into that again
