And how exactly can you prove a random occurance from not happening anymore instead of yourself being very unlucky?
I just tested it myself, gave my DK wisdom lvl1, levelled up and checked the skill points.
Playing in Hardcore, both chars had 0 skill points, level up, both characters had 2 skill points to spend, so I was very lucky
Second try: DK 2 Hero 1 skill point
Third try: DK 1 Hero 1 skill point
Fourth try: DK 1 Hero 2 skill point
