If you grind a lot, eventually you have so many skill points that you have every skill, and just have a pile of additional ones unspent.  
  
It would be nice if there was a very minor, but tangible, benefit to having additional skill points.   
  
For example, something on the level of: every 100 unspent skill points grants 10 max HP, or 100 unspent skill points gives 1 hidden AP - you know, something super minor that will not make players feel compelled to get more skill points, but also won't make you feel that your spare skill points are totally useless. Or maybe total skill points could contribute to your family fame?   

I would not ask for any extreme benefit. But BDO is a game where many tiny things all add up, and you can progress in many ways. It feels a little strange when you have every skill and no use for more points, but still get more points. So it would just be nice if having more skill points was still a cool thing to have.  

yes, it would be nice. thats how you know it won't happen. :)
