If you get 10 PD , you'll hit strong , but you won't hit a shit ... the crosshair will increase after like 0,25 sec after you would have drawn your bow .
Go 18/21, that's accurate, quite balanced , and if you go to level 33, you can get PS like me.
And ... if you begin , don't take a longbow ... rus is easier to man , because cRPG's mechanic makes longbow extremly hard to man compared to other bows ...
If you don't want a dedicated archer , go 15/24 with horn bow , that's decent ... but you won't make a lot of damages...
