I have played very much rpg games.
Most rpg games don’t let you put skill upgrade free from start, you must fist open the skill =)then put the first upgrade =)after open the second upgrade and you upgrade it =) after open the third till you fill all upgrade you need.
Some times you put extra points to one upgrade and then let you open next upgrade (here you do it when you want, they called SKILL MASTERY)
Here in 20lvl you have a complete 4 skill build or the option to choose what upgrade of skills you want.
So if you think that 1 upgrade or skill is not good or useless feel free and don’t us it.
