No, because I am only referring to my own players, not an entire playstyle. I would be surprised if anyone objected to you referring to your group as "skilled players", as opposed to using the term "skilled play".
I'm a white male. Saying "Fanaelialae is smart" is not only fine, but also demonstrates that you are a discerning individual of impeccable taste. Saying "white males are smart" is not okay, for a bunch of reasons including because it has a significant implication that anyone who isn't a white male isn't smart (which is undiluted horse excrement). See the difference?
