I was thinking that once someone heroes they should be able to earn practices for every X amount of XP earned. That way if they stay active and keep exploring and doing things they can earn enough practices to gain convert into a train. 27100 per practice is not enough though, my current TNL at hero, about four times that would make sense.

This would reduce the stress of conless at Hero and make for more options to get a long lived character other than cowering insanely or becoming the leader of a Cabal.
