Let's do some math. Say a guild transfers 40 people? They make 1,000. You quit because of it and stop paying 15/month. That 1,000 is equal to 66.67 months or 5.55 years. I would assume they aren't worried about the 5.55 years it will take before they lose money on that transaction. If you were not willing to go with your guild, chances are you weren't going to play another 5.55 years. If it was just cash, you could suspend for 2 months ($30) and then pay the $25 and be $5 ahead. Heck WoW may not be around another 5.55 years or it may got FTP by then or who knows?
