This is burning up the general forums topics where admins are deleting threads left, right, and center from angry players. It seems like this, aside from when they wanted to reveal your real name on the forums, is one of the few things which 90% of the community is against and for good reason.
Blizzard has to be so blind by greed to start nickle and diming their players through a method they introduced to encourage social gaming which should have been a (free) feature right from the start. They either lack foresight or saw dollars instead of a happier community who were screaming for a feature such as this to come out.
Whether they charge $1 or $10 for this is simply unacceptable and sets up a dangerous precedence when it comes to what they will charge for next such as (non-expansion) content updates. While I would find that hard to believe a couple years ago, it's now a real possibility.
Pretty soon, they will simply change their subscription method to:
WoW Light - $15 - Standard account with no premium perks
WoW Plus - $18 - A combination of standard account with one premium perk
WoW Platinum - $22 - Features all premium access
Bottom line is is that premium based subscriptions should be left to the F2P games which rely on microtransactions to support the developers which, in turn, benefits the community. In no way does Blizzard need financial support on top of what we are already paying in subscriptions.
What makes this such a glaring scheme to capitalize on is the fact that they only decided to implement this right after it was announced that 600k players left. No doubt they need to fill that hole. I suspect the same will happen when the next wave of players leave and they decide to allow BoA items transfer to separate servers for a fee.
