This little girl doing 30+ pushups in heavy full plate armor just puts me to shame. She just got accepted as a shielder warrior as well (pacing is kinda fast I feel, she did a speedrun of that warrior training).
Litty's amazing versatility means she doesn't have to overlap roles with Roma when they're in a party. Roma can focus on DPS while Litty can tank if necessary or switch weapons and go DPS if more damage is needed. Against small numbers of enemies they'll do fine, but now it's starting to seem like they need someone who can do AOE crowd control skills, like a mage.
