I like the idea of fast paced travian.
I would to see some weekly team goals awarded with points (most poinst and the end of the round wins) ->
Kill more robbers,
Build new villages,
Catch most animals
and more like that...
And if there would be more (much more) speed servers the amount of players would not be so high (like the current comx5) and servers might work normally.
But I think they can't make worlds to be only for a month, or two. You see, the main income for TK is from players buying gold. And if the round lasts only a month people will not spend as much as on normal world, thus lowering TK income. I take this back. With servers lasting only a month, there would be (I suppose) much more servers a year (or each month) so it would balance itself out.
