You must be truly delusional if you think NA and EU are similar in size. EU always had a larger player base throughout the years and while both communities are definitely way past their prime in term of the overall activity, EU is still ahead from a fair margin, number wises. They have more events, both casually and competitively speaking, and more players on public servers. That has always been the case and will likely always stay the case so long as both communities are alive.
On the other hand, the 'skill gap' between NA and EU is an endless question which serves nothing but filling forum dramas for the usual cretins who know no better way on how to spend their time. Some intelligent people (though not many) have made some valid points however the years but realistically speaking, there is no way to demonstrate anything, therefore, no real interest in arguing about it.
As for the rest, if you don't know what you are talking about, keep it quiet.
