Other than unlocking abilities, or adding composite points to boost accuracy, what does putting more point into slash do?

IE, if I stopped at 29 slash, instead of 34 slash, would I see a difference in damage, or does point into slash not affect damage, only accuracy and defense penetration (although I heard increased points into weapon skills does not affect penetration of defenses).

its suppose to raise Weaponskill (this is your boosted accuracy)

mythic never fully explained/displayed this.
the only viewable weaponskill statistic is whichever your main one is.

that is to say these are the things that will not appear:

shield
dual wield
left axe
all spellcasting lines

however all it does is it effects your hit/miss ratio against your opponents weaponskill
so going higher than your composite rating of 50, does return benefits, but with diminishing returns.

Is this true for all classes?

For instance, is Minstrel - Slash: 19 -> 20 just an increased chance to land hits on opponent and no +dmg?

Until you cap composite 50 weapon skill line, your damage will have variances.
Apart from weapon-skill increase, it will also slightly boost your average damage as well.
