There isn't any easy solution for this. If you will combine servers, people will be angry, just imagine ranking points..
If you wont combine servers, there will be less and less ppl and no new players
Maybe you can give some biiiig benefits to new players, but what? You gotta say that it is almost impossible to be fast UFE without paying, and u gotta say it's almost impossible to be noob and play. You will be dead XX times per day. - well, but I dont think the solution is benefits for new players.
There is other possibility - do something for ppl who wanna start with this game, maybe u can make new server, but YOU CANT, cuz when u do this, a lot of ppl will stop playin on their current servers and will play on new server, in few months, it will be the same as before, but population of older servers will be smaller - wrong idea again.
I am kinda dissapointed of this situation, but THERE IS NO SOLUTION anyway. :(
I am really sorry for this long post and my english, both is awful :D
