In my own opinion… No. They don’t make the world feel bigger, they make the world feel longer. I think the current live portals are fair.
I may not be a mage, but I think I have just a little less portal power as them currently. Engineer portals + portal access from hubs (Dal / Org), Org portal shirt, the toy that ports me to Black Temple, and I have the scroll to port me to Hillsbrad. (I might have more I am forgetting)
