I had 720 skill points maxed on my bard and I was trying to gain up discord. Which happen to be 101.3. And last night I discorded cu sidhe's for about 5 hours and not one gain!!!! So for some reason I decided to drop all my extra garbage points on a soulstone fragment and flush all them. Which brought me down to 531 total and today I've gained over 1.2 so far in about 3 hours. Don't know if it was the game last night or not but I even went as far as to kill myself to check it and still no gains last night!! So if ya get stuck maybe try to soulstone a few unused skills and see if that works.
