i think there should be a chip and chase kick as well as a grubber and cross feild as well as the obvious kicks

more movements on the trick stick e.g step goose step spin fend drop shoulder  and each player should do this difrently e.g masanga dosent step like lomu and a foward dosent step like a back

keep the quick throw and off loads

star players should have star move e.g lomu running over people rokokokoe spin  masga goose step dan carter kick just using thoes players as examples. manual turn overs if 1st to u ruk

more debth in the back line

ref on feild

more options at break down

tackles should have more options e.g spare tackle, shoulder charge, around the ankles, ball and all, diving, tackle ankle tap

selection on defensive shape e.g sliding, wide, tight, rushing,

players stats reflectid better on the field and more acurate

i think what will attract alot of people is something like what fifa has with the become a pro where you can pick a player or make a player and play soely as that player threw the season, but i think you should be able to have this option in quick game also where you can choose to play as a hole team or as an individual, and when you choose to play as an individual or in be a pro you should have a 1st person camera veiw where the view is from your selected players eyes so its as though you where that player on the feild.. abit like fifa

also a 7s season would be amazing if you could incorperate this and a manager mode mutch more teams and and compatitions and mabe the top 4 teams fom each premiership e.g super 14 guiness premiership etc etc the go into a new compatition (world premiership) and play off for a world club trophy

 

and for loading maby have it like fifa accept insted of the goal keeper have it 1 on 1 with the full back or mabe 100m sprints with some of the speedsters

just a few ideas that you could eleberate on to improve the game
