I have lost recruits at div 3 that I spent anywhere between 4000 - 8000 on gaining interest. They suddenly turn yellow the last day before signing starts, and eventually sign with the other team. It isn't always about thinking you have a recruit in the bag without spending any money.
Now, I am fine with this being a strategy, but I agree with the above posters that the formula should be increased that grants compound interest. The longer I have someone, the greater the interest. People can still steal recruits, but at least there is a reward for recruiting over time and it will make it somewhat more difficult.
I also agree with the above posters who point out it is usually repeated by the same coaches. I don't get mad, or even. I just move on. However, the game would be more enjoyable if recruiting were cleaned up a bit. I keep hearing how recruiting doesn't need any work, but this is an obvious example of an issue that adds nothing to the game and could be addressed very easily.
