Re: 8pt CSL
I wouldn't say useless but Dex is more useful. However, there comes a time in most characters career's that the player has to say enough is enough.
My longest running character topped out at 35 dex. He also has 2 overall, 2 all combat, 2 HTH combat levels and 2dcv levels tied to his acrobatics.(a hangover from earlier edition I know)
