Considering SCG long supported legacy and has continually called for reserve list abolishment I'd definitely not call them scum bags. Legacy never would've been what it became if it weren't for them. At the end of the day though they are a business. And legacy events draw less players which means less people at events to buy from/sell to along with the fact that many legacy players don't buy nearly as many cards. It's disappointing that they've come to this conclusion and I hope that scgcon legacy events turn out to be sweet, but this really is probably the right move from a business standpoint
