While I was always one of the people that stood up for the dismissal of "the slippery slope" and things like "Blizzard is a business", etc, but I might just have to go back on my statements.
Your previous premium features promoted aesthetic and QoL changes, and nothing to really complain about since they were nothing but convenience, mostly aesthetic based and not enjoyment altering features (my point here, is there's nothing stopping someone from faction/race/sex/name changing by creating a new character and doing it the ol' fashioned way. If we don't want to pay for the premium service, we can put the time in and get a positive result for both of us. Hence convenience based)
However this premium service is treading dangerously close to impacting the actual enjoyment of the game for a lot of people (I'm not going to go so far to say it's damning). Sure, I can server change, but only encompasses a single server. This goes beyond the previous convenience/aesthetic based premium features, and starts getting into actual gameplay enjoyment unless we pay for it.
I will add that I am not one that would use this service even if it was free (I admittedly, don't have RL friends that play WoW, or cross realm friends). I understand that it's premium because "its a complex task", but I think you guys are starting to grab for straws to keep this game appealing, and doing so in the form of additional payment trying to milk the dying cash cow for all its worth while you still can. For shame Blizzard.
Complex and Possible expensive features? You obviously haven't played any other MMOs or just don't know much about computers.
I'm confused whether you're agreeing or disagreeing with the poster you quoted, but I'll humor you.
"These other MMO's" don't have even remotely the same level of attention and demand for their games and features, allowing much more time to spend with frivolous demands from the playerbase like appearance tabs and player housing.
