As the title said, I would wish an increase of the traveler maps.

Those maps are having a ridicolous long cooldown time anyway (usual one 6 hours, ok Oasis 3 hours, but they will be patched out sometime eventually), so at least increase the range so it would be actually much more usefull if you'd change the range to at least travel to neighbour territories.
Except for the sea there are some exceptions, right now you only can travel within a territor.

For exmple I had my character in duven, had to go to Velia but only had a 30 mins time before I had to go, thought I could use the map to at least shorten something to be faster. In the end it was completely useless and I had to go the whole route myself because there was no single usefull spot to fasttravel.
And NO! I don't have those much more ridicolous rng based T9/10 tons of grind/expensive partly p2w horses...
Neighbour territory once in 6 hours would be already great - could have travled of duven to glish at least to shorten it a bit for example.

SO you want fast travel?

Then use the transport character function.

Yea which is taking, depending on where you are starting and want to go, an hour or alike...

Traveler map is bassically a fast travel. Just without usefull range.

So the system is already implemented in game. Fast travel fast but with long CD. Fast travel long w/ no CD but long wait time. 

It would probably be a better idea to lower the character transport time to 30 minutes, but making the travellers map longer range doesn't really make sense.
