This would be valid if not for the ads also being on the in-game store. Even if you didn't buy any of the packs, I'm sure most people likely opens the store up and looks at the new items for sale from time to time. Again, I think a lot of the "I didn't know!!" talk is people feigning ignorance. I guess they think Bioware will be more likely to give them their way if they pretend to be a victim.
Ever see ads/posters for fast food? The actual food you get is NEVER like that. The gear in the ad isn't even labelled. Arguing that an artistic impression is supposed to look 100% like the finished product is insane. Just not as much as arguing that everyone who plays is responsible for checking the forums for hints that a change may or may not come.
