Please yes. The Airtrain is such an incredible rip-off, especially if you make the completely rational mistake of assuming tha your Go Card is going to be the cheapest and easiest way to pay. In fact it's more than twice as expensive as paying online ahead of time, and 5 times as expensive as it would be via regular Go Card prices from the CBD.
And none of this is communicated clearly. You can't even easily make an educated choice. It's a system that needs to die.
