...the new staff system makes the staff market into a new bidding war wherein as far as i can see, you can't sell your own staff (i think) and the staff system is looking more like a big money vacuum, so to speak...
The crucial factor is the extent of weekly or periodic salary rise... if it is on the order of one hundred bucks, it will lead to a bearable increase of costs, and you'll be able to keep a good specialist for long time... but if the cost rise is a percentage of the salary, well, very good trainers might easily become something you get for maybe half a season... This might be realistic for doctors, especially because one might look at the market and hire Dr. House to get back healthy an important player, then fire him... but besides this possibility, I'm concerned by the new system, frankly speaking.
Sincerely
Giuseppe
