I think it will be much more difficult for new players to experience wvw down the road. Zergs are not going to accommodate mountless players like they are doing right now. So if you are new in a few months you will be on your own.... one mountless inexperienced player against the hordes of mounted experienced players. I think it could be a very frustrating experience and turn away future wvwers.
I know you can earn the mount in eotm but will anybody be playing eotm in a few months after most people have their mount?
