Can someone please check the % of primary skills learned? I have made limited test and found that the information in this article is wrong. according to my limited test, the correct percentages for after level 10 are (i.e. from level 10 to 99) are: 30% to increase attack primary skill, 30% defence, 20% spell power, 20% knowledge.
I will be wating another test, otherwise I will change the article if nobody answered
Edit: actually, I have just checked heroes manual, and it states the same information
