Tipping for Ports: Apparently I've Been Doing It Wrong

[Xruptor]

On Green/Teal I must be playing the wrong game. I've always been told by the folks in my guild and even by some of the teleporters that 4pp or 5pp would suffice as a tip. I've never heard of this 1pp per character level. I didn't even think people wanted that much money for a port. Wow all this time I must have been tipping wrong if that's the expectation. These porters should just PUT the amount they want instead of saying "FOR TIPS".
