When is your attack rating "too much" ?

[Elwin]

you can barely reach cap it is 300% indeed but its 3.3% atack more for one atack points more then ememy defense, so u need 90 attack when enemy defense is 0, but level 5 units will have 20-30 defense and with hero its another 20-30 so your 80 will reach just like 30 in crucial fights and its only 100, so far from cap . With dragon arrows u might reach that with hunter tough
