@Nik, I don't have time to be repeating myself over and over. Please read my numerous posts again in this thread, if you didn't pay close attention.
In short: It matters less which "Dinaric" cluster (North or South) is more common in the Balkans or East Slavs. Percentages are meaningless. What matters is both are present in considerable amounts in East, West, and South Slavs. Considering that North of the Carpathians there is many samples who are ancestral to the "Dinaric" clade (I-CTS10228), and nowhere south of the Carpathians, it's origin must lie North of the Carpathians. And also considering it's young TMRCA, it expanded as a part of Slavic migrations. I have nothing else to say.
If you're one of the Albanians who carries this clade, you have nothing to worry about, as it by no means changes your ethnic identity. Afterall the Y-DNA represents the origin of only one of your many ancestral lines. Although my Y-DNA and maternal Y-DNA are not I-CTS10228, I'm sure this clade will show up in one of my many other ancestral lines if I test them. The Slavs have been living among us for the last 1500 years. So it is to be expected that we have some genetic input. But in the end it doesn't change our ethnic identity. Just like the Slavs have a considerable amount of Pre-Slavic Y-DNA, but in the end they are still Slavs. There is no present Balkan population that is genetically 100% the same as Pre-Slavic Paleo-Balkan populations. However, considering the data, the Gheg Albanians are to the closest thing we have.
