So for the Haka it's great to have all the players in the All Blacks team doing it. But for the opposition team instead of only having the starting players, it also needs to involve the bench.
For career mode, it's great but needs more games for the international teams. Instead of playing just the Rugby Championship for NZ for example. There needs to be a June series where a northern team plays NZ for two games, and when it comes to November it needs to have NZ playing at least 4 teams. Needs to be different each year.
Also, have a somewhat Lions Team doing the tours every 4 years. Doesn't need to be licensed but a team with the 4 nations doing the tour rotating every 4 years while also having at least 5 practice games before the actual test series.
