actually I have an idea... !
New players should have free evasion for the first month. (and no cata attacks allowed for the first months as well)
And by new players I don't mean that you could just reg with a new email, but new players who dosn't have any medals.
that would maybe keep some of the new players to spend more time in the game, before they go inactive, becomes natarian villages and then are chief-ed by the top players.
There is nothing that help new players, and the build in guides are useless.
Build a cranny, no build 10 cranny's if it's your first server, in every city.
and pray that you are not spawning next to a top raider... it's an unbalanced game.
Pre registration for veteran players, so they don't know where they spawn could be another, so if your email is known by TG, your spawn city will be far away from beginners...
but then again, it would no longer be Travian Legends, it would be a game like so many others, and we all do know that TG is all about the gold ;o)
