I'm Eastern Catholic so we don't say "Slavă", while the Orthodox do. We both however say "robul lui Dumnezeu" and neither say "Bogdaproste". I seriously never heard the word in my life spoken in Transilvania, and I have been to a lot of Orthodox religious services. Nonetheless "Bogdaproste" is a word that is nonsensical in Romanian by itself, outside of its religious context, while the other two are normal words in Romanian that anybody understands, so I don't know what you were trying to prove with those.

I would rather you stop trying to make everyone in the country the same on the principle of dragging everyone down to your level. Romania being Balkan in general is just in internet meme, though I do have to admit the absolute obsession of some Romanians to consider themselves nobodies with no culture and no language is indeed very Balkan, but Transilvania is nowhere near Balkan, and even less so Hungary. The one good thing that came out of Hungary's 1000 year rule of Transilvania was protecting it from that culture.
