Actually it would matter, since of course Russia could bring the whole team by themselves, but they won't have a leader, that's all. All of russian-speaking regiments which played competitively were leaded by ukrainians, that's a fact lmao (apart from 1y Nevskiy as I know, which was like Tier 3 regiment or something).
Also bulgarians played last NWWC with Russia as one coalition. That's adding a chance for them to play with us as well.
Also Shogun (the only active latvian player atm) and Slavic (the only one ACTIVE & COMPETITIVE macedonian player atm) both were playing for Team Ukraine.
If we will bring all the facts together, we've got a really good point of playing with each other yes
