And to expand...
You, Smirt have a reputation within the game and a legacy. You've had success by playing the game system, using game exploits which the engine allowed. All credit to your success and approach.
The problem is though, Smirt, you chose to play the game engine, not players. That's valid, but you're not an idiot - you knew full well at some point those exploits would be addressed; you also knew that's something the community wanted and supported.
By adopting the approach you've indicated, complaining and quitting, you are tarnishing your reputation in the game. It comes across as though your only concern is not being able to exploit and succeed rather than putting the hard work in to rebuild your roster and get success.
Looking at your roster now, anyone taking that team over should you go - and indeed, any of the teams you abandoned - will have a massive task corrected the rosters you leave behind. Massive. I'd consider taking one if in a league I'm not already in as I enjoy that kind of rebuild, but... I hope admins show leniency around any cap issues.
I hope you don't leave, I never pegged you as a quitter, but if your only enjoyment of the game is success via exploits, then you've got to do what makes you happy. I thought, given your inventiveness around the exploits, you'd have taken this as a challenge to succeed whilst rebuilding, not being able to use certain exploits.
