Refs taking the easy way out, they know it will be shit storm if they make a certain call against certain teams. In other words its easy to be kicked when your down. Parra know what I'm talking about.
I agree, I haven't felt there was an anti Warriors thing in calls as such, as other teams get stiffed on a regular basis too. The Sharks are the first that spring to mind, and Eels of course when they were struggling.
What I think is that there are 3-4 utter Darlings of team who get the 50/50 calls pretty much most of the time. Unsure what you can do about it, unless a few in the NRL have the balls to face a fine and throw that into the media, it might embarrass the officiating to reverse for a little while.
