Maybe is complicated change our team of server, but is very easy to have the option to select (like in lots of games) a server to play when we start.
At now if I invite a friend he start in my server, because there's no problem in the level 1, the problem is with 11 millions of players see hundreds of teams doing a change of server... that can be a caos like is the game, so, as I suggested one day.

-Nordeus have to put the option, to select a nº of server when we start in the game. And, can be interesting to add aditional info. like the level of the Top Server (or if is a new server, 1st season), in all the possible servers that we can select.
That's not complicated.

Too can be interesting add the nº of players per nationality, and will be "we" the players that will have the option to select a server, with more players from our country, and that's = with better schedules.
