Well like I said, I can't speak for sure about these countries with so few users.
I do open with saying that I'm still completely against the merge, but a common league seems like the reasonable way to go if a merge were to happen, of course on the condition that NT, U21 and flags stay untouched. But then again, how would this work ? What about the national tournament ?
Also I'd like to point out that with a common league, there would be a common draft. We have so little high potential players as it is, the way that players names and flag will be generated when they get drafted to their respective teams won't work. This will lower the NT competitions even more I think
