the main issue here is how to engage people into NT training
agreed.
you can't keep a 450k on a farm because that farm should play at least in second div and this is very unlikley to happen for periods higher than a season
counter-example:(7558003), $540k, 7 months in division IV, alive and kicking
Sure, I did not say it was imposible. I did say it was unlikely, and I still think that.
Farm teams might survive for longer periods, but how many of them could you manage to have for a specific country? Managing 8-10 farms like that one is harder than making good runs in the WC without farms :)
Still, farm teams are an issue but I don't really think is something the BBs really consider a problem. If it were like that an easy solution had been aplied long ago (Like limiting that amount of salary paid to a given player cannot be higher than, say, 80% of total salary share for more than two consequetive weeks, so you can still give some freedom to managers and avoiding the most easy form of farming). A typical BB answer would be: "If we thing that farming becomes a dominant strategy for NT, we will look at it and found a solution" :D
