Its clear that Mighty never went to look for any members. He was playing GF's with team russia for weeks before the coalition was announced and clearly had no intention of looking for players and forming team yugo.
The argument of "there weren't enough signups" doesn't make sense in that case. Mighty never actively looked for players and maybe even "sabotaged" (for lack of a better word) the formation of the team. There clearly seems to be a big enough group of players that would've and could've made a team. The other serbs clearly don't want to play for russia. Dixon added them, but they were all 'inactive'.I'm pretty sure they just don't want to play for russia.
And still, while a lack of signups might prevent team yugo from making their own team, it in no way justifies a merge with Russia. The only real connection is that Yugoslavia was a former USSR satellite state. And if that is the only thing justifying the merge, then any other former soviet state could be allowed to merge with russia. Might as well make a team USSR.
The only counter-argument that Mighty has is some racist nationalistic shit in serbian. Which ties in to another argument you guys raised: that team yugo would disband/split up mid-tournament. If they do, it would be because of nationalists like Mightypain. So in my opinion you shouldn't allow Mighty to play for team yugo, just let him get what he wants and him play for Russia. But let the other serbs form team yugo if they really want to. This would fix the situation and give each party what they want.
