Same. It doesn't feel so bad atm cos I had a 60 pass from when MoP came out and my wife got it me for Christmas but it runs out on November 5th so then I've gotta start paying. I will never play retail so it does feel like I'm being scammed a bit.I really wish there was a way to just buy a sub to classic wow only for a one time purchase. I have 0 interest in retail and I'm playing other games at the same time along with real life commitments so paying $15/month when I only got to level 20 in one month (plus some alts) feels slimey.
The guy who made it is really helpful on Discord if you want to join his channel.I can't work out how to use that sixtyupgrades.com site at all. :s
