I'm using a Drakania and, at the moment, I've got 1875 skill points. All the skills I'm using for succession got maxed out at... 1810 skill points, I think. I keep earning skill points while I grind, though. At some number of skill points, you'll have enough for any combination of skills, right? Instead of earning extra skill points that are useless, we could earn a higher rate of combat experience instead... or something else that's useful. 

I'm sure there's someone out there with a character at level 65 with like 5000 total skill points but only using 1800 of them. Is there a cap? I don't even know. If not, what's the point of all those extra SP? We earned them - let's make them useful.
