In one of the first seasons of BB, the BBs said that they didn't want to see players like the "divine" of hattrick, that's why they decided to increase in an exponential way the salaries of the players in order to give a "bonus" to everyone that trains multiskills players instead of monoskill. Another point is that the difference between a lvl 19 and lvl 20 is very low compare to the difference between a lvl 1 vs lvl 2, it means that there is no reason to boost some skills over a certain lvl, if you want to do that you've to pay. Imho the salaries could be ok they've to cut the money coming from merchandising, tv and arena, the difference between last season and this one in my case is +200k/week (even more) and the salaries didn't increased of 200k.
