If you had read these threads properly, you would understand why this does affect you. As soon as you have the option to bypass levelling via an additional payment, there is no incentive for Blizzard to make any effort to improve how levelling works. So the next time you come to level, you will be faced with two choices; pay them extra to bypass it, or just accept it, regardless of how bad it is.
You only have to look at the problems with low/unbalanced server populations. It has taken them years to even start to address the issues, and the way they have "solved" them don't really address the issue. And why has it taken so long? Because they have paid transfers, and are making a nice little profit off them. If those paid transfers didn't exist, there would have been much more of an incentive to correct the issue earlier.
A lot of people complain about how F2P games work, with good reason. But what you have to understand is that bringing paid services into a subscription game makes it work like a F2P game; you get all the problems, but still have to pay a subscription as well. Is that really what you want as a customer?
