In Gorshkov's reply regarding Artur's participation in Worlds, there did seem to be a bit of reluctance, which is understandable but not necessarily leads to better decision. Getting 3 quotas is possible, but it's not something that largely depends on themselves. Let's admit that at this point, such "reliable" skater does not exist in Russia (and 99% of other federations) that each time you set a task that's near his upper limit but he's unlikely to be crushed by the pressure. Personally I don't see anything wrong with following Euros results, both to give respect for selection rules/the Fed's own authority, and to avoid stressing out everybody potentially in the mix.
As a fan of Artur, I prefer he goes to the bigger stage at Worlds, but will be glad whether it's WC or WJC as long as he's exempted from whatever qualifying competitions. One thing I'd be a bit gutted about, though: if he gets a bye for WJC, one of Mozalev, Samsonov and Gumennik will have to be left out. All three are worthy competitors for WJC hoping to gain momentum from the concluding event of this junior season. It doesn't hurt to give opportunities to more promising youngsters and expand the selection pool for Worlds 2021 and Olympics 2022.
(A few words about the Samsonov hype that I've been feeling the urge to speak. Just a reminder that it roots from circumstances before this season. It seems to be dissolving with him doing no better than domestic junior rivals. Through the scoring at Senior Nationals, RusFed has conveyed the message, quietly but clearly, that he does not deserve that much favor yet. Before Senior Nats there were people complaining about upcoming huge boost for him and posting somewhat bitter predictions that he would get on the podium, as if by reinforcing the formed impression (or rather, to some extent, illusion) it must become true. What for? With some older juniors rising to the challenge and more than one younger supertalent likely to emerge, I don't see why RusFed must think Samsonov is the life buoy they have to cling onto in the Men's discipline. No need to panic way ahead of reality.)
