What lv13-16 skills do you think are crucial?
Soulsap and Null Res are very powerful, but not mandatory. Before lvl16 enemies, certainly not. I usually use one of them just for the pleasure of seeing really high numbers. They make the fights EVEN MORE one-sided.
It's possible to do crazy amounts of damage and disables with only lvl1-10 skills.
Rangers can also destroy enemies without those skills.
I can only think of both skills being mandatory on weak or not very diversified party compositions, or on parties built around them.
Do you mean it's crucial to be overleveled at some points? I'm certain that not receiving the Guardian's XP won't make the party nowhere near underleveled.
