Yep. There's a school of thought among some that it's fair to use MB against teams who have "visa" players. It supposedly offsets the unfairness of a player having paid for a team with real money.
At first that seems reasonable, but it's still flawed logic. Every player worth his salt in this game knows there are ways to acquire those "visa" players without actually pulling out your credit card. So how do you plan on discerning whether those visa players in that lineup were actually paid for in real cash, or are there because the team manager played the game strategically well enough to be able to fill his squad with them credit card free?
So what happens then, is a guy who has planned his route to the top strategically, worked tirelessly to perfect his strategy, and gathered sufficient rp through intelligent game play to be able to acquire the right players, is defeated by a guy who has done none of the above but can slide a bar all the way to the right. Such skill. Much wow.
