I think she still holds benefit in the Labs if you pair her with a strong queen P, and (if you can) a strong Khan. Also, from my experience, there are several situations in royal arena etc. where she could be pretty helpful. I'm about mid-game right now. Working through lance and Mulan as well as ironheart gear. one server I have adam the other I don't, both seem to be progressing relatively the same. Maria would boost me up a few Royal arena foes I beleive and probably straight through the ironheart gears.
