GameInformer's, Matt Bertz gives us the goods on the new trading interface in NHL 13.
Once you propose a trade, if the opposing team doesn’t accept it will give you feedback about how closely your offer comes to being feasible. In my experience this could still use tweaking. Because Montreal was in the market for a top-six forward and was willing to give up its first round pick, I offered Pierre-Marc Bouchard for the pick (an admitted reach) to see how far off this proposal would be. The GM said that they were very interested but I had to sweeten the pot. I tried adding a sixth round pick, and that wasn't enough. I eventually worked my way up to offering Bouchard and a second rounder, and I was still receiving the same feedback even though it was apparent that my first offer was much further beneath their expectations than they originally let on since they were still rejecting my much more generous offer. Hopefully EA Canada has time to refine this feedback to be more specific.
The NHL development team also opened up about other changes its made since we saw the game a couple months ago. Based on early fan feedback on NHL 13’s direction, the development team also decided to change the player ratings to create more of a gap between the star players and the average skaters in the league. Franchise player like Sidney Crosby are still rated in the 90s, but the average ratings of third-line defenders are in the mid-70s instead of the low-80s this year.
