Of course. I was talking about the optional part of the mount deal (the mount itself). At L60 you still gotta pay 90g for the L40 skill before you can put down cash for the 60 skill. --- Don't worry, eat pie!
Before the introduction of riding skill, it used to be the other way around. You could buy your mount training at 10g and a mount at 90g, or just get the training and skip the mount until 60. Now there is no point, so just get the mount. --- The statement below is true. The statement above is false.
