AR below 8 already does give a bonus. An increased one if hidden is being used. Since forever.I know, but the bonus should be more and it should include ar8. Low AR will never be the meta or farmable but giving it a small boost would be nice. It might encourage people to play the thousands of AR8 maps there are.
In my opinion, AR8 should also be included in this bonus. The standards nowadays are AR9 and AR10, anything below or over that is hard for people to read. Yes, it depends on the map (more precisely, on object density), but in most cases AR8 is quite difficult.This.
