What on earth gave Funcom the idea that 5 Vet points for summoning a travelling trader once only would be good idea ?
Who would use such ?
One time use of such is not even worth one Vet point. When are you ever in such a dire need of Trader that you would use Vet points to summon it just once?
If it was permanent thing that once bought then you can use whenever you want then it would actually make sense.
