Word of Eupedia admins is not holy and without errors. It says "could have been spread by Goths".
Z63 is actually very, very small part in our I1. All Z63 in Serbia and Montenegro descend from same Macura clan. And because their oldest origins are somewhere around Berane in Montenegro, I think they are descended from German Saxon miners, who came in large numbers to work in our medieval mines. Berane-Mojkovac was very important mining town- in medieval days it was called Brskovo (
http://en.wikipedia.org/wiki/Brskovo ). Even its name is of German origin- "Biergsau", completely inhabited by Saxons, who even had their own priests and prince there. So it is most likely of Saxon origin, not of Gothic origin.
Most of our I1 is I1 P109, called "Drobnjak clan cluster", with value of 0 on STR481. Man with same value was found on Sicily, and Nordtvedt estimated that our carriers and he descend from same man who lived 850. He was definetly a Norman.
You can find all of this data on Serbian DNA project:

I definetly do not expect that Normans (who left almost no influence at all) have more of their haplogroup than Goths (who, according to you, carried z63).
Since Z63 is left by medieval Saxon miners, and P109 by Normans, then we have to find what is Gothic haplogroup, because Goths left much, much more trace than both Normans and Saxons. And most logical theory is that I2a Dinaric came with them, because it perfectly matches their migrations, its age of expansion matches beginning of their migrations, and it also explains concentration pattern of I2a Dinaric in Yugoslavia. It also explains why dominant racial types found in Montenegro and Herzegovina are only found in Germanic peoples.
See all my previous posts.
I don't know why everyone expects Germanic migration-period tribes who came here to be so freaking high in I1, when even modern Germanic peoples (expect Scandinavians) rarely have it...
I repeat again- word of Eupedia mods is not holy, or without mistakes.
Give me reasons why would I2a Din be Thracian/Illyrian/whatever?
Do we find most diversity of I2a Din in proto-Thracian homeland? No. Do we have concentration pattern that fits their migrations? No. Did I2a Din form in their homeland? No!
On the other hand, we have TMRCA of I2a Din 2500 yrs ago in Poland, somewhere around Vistula- proto-homeland of Goths. I2a Din is estimated to have expanded drastically around 2000 years ago- which matches Gothic migrations.
And for gods sake, please understand that place where I2 M423 differentiated into Disles, Isles (found in Britain) and Dinaric simply does NOT match eastern Europe. In fact, from Motala12 bones we have evidence that I2a1b very possibly came from Scandinavia to continental Europe. See previous posts please.
I2a Din is highest in Herzegovina and western Montenegro (those numbers for Montenegro, as I already explained, included gypsies, Albanians, Bosniaks settled in eastern part).
It is also area where we find Germanic nordo-cromagnid "Borreby" racial type as dominant.
I2a Din in Romania is as high as it is in some parts of Ukraine- and IMO it is even more possibly Slavic than Thraco-Dacian.
One part of Goths living near Black Sea was actually enslaved by Huns and never came with rest to Balkans. That is why Gothic dialect survived in Crimea until 18th century.
And exactly in Black Sea area near Ukraine in Romania we have most carriers of I2a.
So I2a in Romania is not aboriginal. It is Gothic/Slavic.
Are we culturaly close? No. Linguistically? No. Anthropologically? No...
