Is it worth leveling whm up to 42 for telewhoring still? i don't really notice shouts for it anymore, but i tend to ignore shouts anyway.
One thing to keep in mind, is that there are more ways to get around the game now. Players can pay a Silver Imperial coin and get warped around, they can outpost to all the old conquest regions, or get retraced back then use the past warp system to walk through a Cavernous Maw (Yup, you can make a little gil doing Retrace-taxi too).
Sometimes a teleport is still the most convenient way to travel though, so there's still demand, mostly during peak hours, or when a new mission or quest sends a surge of players out to one of the telepoints.
