I think that this is a good idea personally but it will definitely have some setbacks to be addressed, I personally miss the days of t3 30k players on a server when things were much more competitive. But there are definitely a few negatives I can see as well which I have listed my thoughts below.
More international interaction
Communication between all players could be an issue without an autotranslate feature in game
I am excited if this becomes a reality, maybe a test server would be a good idea so we can all get a feel for what it is like playing internationally. This reminds me much of the tournament servers however which are the last remaining inkling of competitive travian play.
