Small federations are always at a disadvantage, unfortunately. Javi has gotten where he is partially through sheer talent/ability/improvement, having Morozov and then Orser for coaches (well-known coaches can help overcome being from a small fed) and years and years and years of disappointing results that he improved on year after year after year. Small fed skaters need to work harder and improve more in order to be given recognition by the judges.
And since North America and Asia have become so dominant in men's skating, Javi has become the clear #1 European men for years now. Having less internal competition makes it easier to win those prestigious European titles, and that matters.
At the top echelon of skaters at Worlds, I wouldn't be surprised to see some minor European bias. Inconsequential skating countries need to stick together. It'll be interesting to see how pairs shakes out.
Deniss and Moris (and Daniel Samohin, who isn't here) could all be the next Javier regarding his trajectory. Michal and Alexei are both a little too old at this point and just haven't improved from year to year like Javi has. But the young men from small feds all have to put in the years that Javi has in order to get the recognition they deserve, unfortunately.
