I honestly don't find anything wrong with it, if people are willing to buy it with gil and groups are willing to sell it then its a mutually beneficial transaction. The sale groups pay their own subs and they are in no way, shape, or form obligated to carry people through content out of just goodwill, they don't owe the community anything and to expect that of them is somewhat selfish as well. I find sale groups to be a service, they do for you what you can't do or just have a hard time doing on your own, sorta like hiring a plumber or something.
