I don't get it when people say specialization is for insects when most of the people that are praised and talked about for their accomplishments are specialists. Very few people are known for many things like Elon Musk.
I personally think it's better to dump all the stats in the best areas than spread them all out, because it's better to be exceptional in one area than average in multiple. Gandhi spent all his stat points in WIS and none in STR that's why we know him today. The reverse for Genghis Khan.
