These are premium services added to better accommodate the wants and needs of players. They do not factor into what you get for buying the game/expansions and paying monthly for access to the serers. By no means do you need any of these premium services to enjoy World of Warcraft gameplay to the fullest extent. Should you desire to take advantage of some extra services to enhance your enjoyment of the game though, they're certainly there for you... if you feel it's worth the price.
We've made countless quality-of-life improvements to the game in terms of content, UI, data storage, character profiles, etc. We've expanded upon what you get for your monthly subscription by leaps and bounds since the game was first released, but the subscription price has not changed.
Everything we do and every service we add costs more money than you might realize. So, if we do occasionally add some premium services which are purely to give you more options for enjoying the game how you want (changing your realm, faction, race, name, physical appearance, etc.), we need to make sure there is an appropriate value added to those services so we can sustain them, sustain our business, and keep focusing on making this the best game possible. :)
I don't know of a single person who readily agrees with this stance facing it from a Player point of view. Hundreds of articles have been posted by pundits, players and pontificates alike suggesting alternatives. Some of them still with a cost attached but most of them pointing out facts like the system is automated and costs very little now that it is in place and should generally be free or at least free on a time limited basis to avoid abuse, etc. I'll not rehash them here but feel free to browse the web and see. It was addressed in a relatively recent Azeroth Daily, for example.
We don't have insight into your system but it is difficult to imagine that renaming a character is the equivalent strain on resources that an entire months subscription (or more if paid in bulk) is. Moving a character is even MORE expensive than an entire months subscription! If we were educated as to why this is then maybe we could relate to you position better. Not to mention the condundrum of discussing where the funding of "countless UI improvements" and "what you get for your monthly subscription by leaps and bounds" by implying that "premium" services are paying for these improvements and not by the subscription which is only "access to the serers(sic)." Where do boxed and digital sales of Vanilla WoW and it's expansions factor into this system of paying for UI Improvements and "what we get for (our) monthly sub" fall?
There is an implication that subscriptions alone would not be enough to keep improving WoW, sustain business and make WoW the best it can be. And that the rename, faction change, server transfer services are so costly that they would not be sustainable if you did not charge what they cost now. I know many other MMO's where the cost of renames is actually free, free with "tokens" given out periodically for long term subscribers, or "cheap as free" in that they are less than 2 or 3 dollars American. I understand WoW is on a different scale than any other MMO but it is terrifying to think that, without renames, transfers and faction changes in the $15-$25 range we would not see improvements to the UI and that, in fact, WoW would suffer or need to move to an even MORE expensive monthly rate to survive!
Lastly. I don't think it should be an unmovable, irreconcilable topic to take such a defensive negative stance on. It just seems that stance is very aggressively against any change, so much so that a emoticon smiley was needed to try and lighten the mood at the end of this post. I, again, understand that this CM is famous for being "the cool/mean/rude/snarky one" and putting people in their place to the delight of many forum posters. It's not the route I would take with customers, personally. It is an often made mistake, usually by young folks, to go this route. In my experience, they eventually learn the error of this line of thinking when they are older and more experienced. Age tends to mellow us all and teach the value of seeing things from another's point of view and finding compromises we can all be happy with.
Edit: In fact, the tone and attitude in this post is very different from the post titled "Welcome to the forums. We love you." posted a couple of hours after this response! This post is very "cool" with phrases like "if you feel it's worth it" and "more than you might realize" and the other post is practically wearing it's heart on it's sleeve and trying to get a drum circle singing Kumbaya. Fascinating. I hope the turn of heart continues.
