Currently the revealed heroes have a default value of 2 for each attribute with an additional 4 points disbursed in 2 or 3 skills. Each hero has a 4 in at least one attribute and each attribute has at least 1 hero that has a 4 in that skill.
It would make sense to make the last hero have 3 for every attribute and be the jack of all trades.
Have we seen anything about her besides the sculpt? Do we know who she is? Would it make sense character wise for her to be a jack of all trades?
