Inc 60% flying mount speed - pain in the butt
TBC is a nice expansion, but it does have some stuff I dislike about it. That's why I also agree with dual talent spec to be introduced, if possible.
Another one of those annoying things about TBC is the fact that your first flying mount will have a 60% speed only, compared to the epic one which will be 280%.
I believe that was a not so bold move by Blizzard back then, and they fixed it in WotLK when they increased it to 150%.
My opinion: make that first flying mount 150%, otherwise we will experience the same pain in the butt.
