I'm definitely hoping that with this game or future ***les, stats will become increasingly important to gameplay and strategy.
I should have to think about how I'm going to get over the gain-line for example, and using, say Billy Vunipola to take the ball up should really pay dividends, whilst taking it into contact with Ben Youngs should not really get you anywhere at all. I know that developers already try to do this, but I feel that because rugby depends on these small differences, stats should be weighted so that differences matter and higher stats are rewarded in all areas of the game.
The other thing I'm keen to see successfully implemented again is a form system. I think rugby 08 tried to do it, but It didn't seem to have much impact. Ideally, there should be a stat for form which actively dictates who you pick, rather than base stats. I remember in rugby challenge 1 with Wasps, always picking Joe Worsely at 6 because he had insanely high stats - no need to pick anyone else.
