Thank you! Interesting!
I looked now at the map you posted, and found some more recent paternal DNA than 3000 BC, from the edge of the Dacian kingdom. Unfortunately, there is a lack of data from Dacia's center but are some data from the edge of the Dacian kingdom.
In the interest period 1000 - 1 BCE, I found just a few(8) data :
R1b x4 ................. 50%
R1 x1 ..................... 12,5%
N x1 ....................... 12,5%
G2a x1 .............. 12,5%
Q1a1 x1 ................... 12,5%
I think if we interpolate with the older or newer period data, from the same territories, we can get a better idea.
3000-2000 BCE
I2a x5 ............... 38,5%
G2a x2 .............. 15,4%
R1b x5 .............. 38,5%
H2 x1 ................ 7,7%
2000-1000 BC
(little important, being just one)
R1a1a .... 100%
(R1b, I2a and G2a are mostly subclade of R1b1a, I2a2a and G2a2
For the more recent period, I have only found a single location in western Hungary where we notice the prevalence of R1b and I2a, which is also noticeable earlier.

With these, I think, R1b followed by I2a and G2a seem to be the most representative of the Dacian population in the Iron Age. Possible, little N or Q, but just traces, having only one example.
