It's completely reasonable to check the Dev Tracker 5 mins during a day and make yourself aware of the known issues which may or may not affect you. In this case they stated a month ago it was wrong and would be fixed to match the promo art which also at that time they stated everything is intended to match the promo art. Not doing so negates any credibility to complain when they fix something that was incorrect to begin with and acknowledged to be.
To my knowledge, players are under no obligation to check the dev tracker or ever log into the website. If you can find a statement in the TOS that says that they are, I'd like to see it.
