I doon't thinkit will always add one extra portal - but places that are currently accesible directly from Bristugo would require an extra portal to Aughendell to access a lot of the places that higher tiered players access regularly, if I read it rightly.
I do not read anyone saying they're going to increase the prices of portalling - merely that some will be proportionally higher than others - but that exists right now. you can get to Bristugo for free from some places, from Bristugo for half price, and from AI to a lot of places for free .. it is a relative term - not an indication the prices would have to increase (as I read it).
