Once again, each one defend his own interest...
International clans want a single continent as they have worked to have multi continent members,
Single continent clans want to split the server cause they fear to be ineffective against the other one.
I'm not in a clan, and i have participated in NA and EU battles, both was funny, high ping was harder ofc, but with some training you can achieve to anticipate.
I don't see any problem to have only one continent, it adds strategy and tactic, it adds alliances NA/EU (not only on forum).
Strategus is on 24/24h, fief owners have to deal with it.
Btw, ofc 2 continents will split even more the community.
