Yeah I'm nervous that the 125k salary player I bought might have been the wrong choice and maybe I should have expanded my arena first. He did raise my merchandise levels tho :D
That was my mistake. I bought a player with a salary like that to try and stay in Div II in Season 18 after a bad season and a half, and trying to hold on to him to promote again it caused me massive financial hardships and it took me four seasons to recover.
It was doubly hard because I had made the playoffs almost every season since Season 2 - and even now I'm not as competitive as I would like. So I'm going a little more slowly, training players up and saving to buy one more young, solid player at a decent salary level.
