It was nice to (finally) see her in get-up, even if it did feel a little cosplay. Especially in that episode where she's the Klingon messiah mom. I think Quark looked better in armour than poor old Tom
I think it made sense that she would not look entirely comfortable in Klingon gear, like a high school kids wearing a tux to the prom. On the other hand, I think that her performance should have been closer to Suzie Plakson's when it came to dealing with Klingon issues: knowledgeable, but critical.
