When the new textures go live, presumably in 7.6 next week, I expect them to also have a grace period of a few weeks where character facial customizations will be free. If they do not do this then I will be extremely disappointed in their lack of transparency and obvious money grab. But, I'm pretty sure they'll offer free or deeply discounted customizations.
The price change does not bother me at all. However, the lack of communication is a huge problem.
