I think the first thing we all have to say is thanks for creating a rugby game when other big developers from EA to PES developers do not see a market in it.
A few changes I think that are required
The Lag and Frame Rate. It's hard to play in any mode when it's laggy and has no smooth flow when in a match. It needs to be alot smoother so people can throw passes properly, can decide to move the ball down the line.
The player creation. When changing things like the complexion or ethnicity or tattoos. It's slow to load up each as they it's trying to find them rather than it being completely smooth and therefore makes it hard to create players properly.
Censored names. Alot of names are being censored for no reason and therefore we need to have a sensible adult content beholder. Maybe have it in the settings so you can create people like Pocock and it not see cock as being offensive.
Some likenesses have odd complexion like Jordie Barrett. From the head up hes bloodless.
Some players have no been face scanned which seems odd like Ben Youngs, Manu Tuilagi, Anthony Watson etc.. is there a reason for this. Similar to that the Warratahs have no official license?
Having the ability to do phases with the forwards off a ruck or close to the ruck rather than passing to the fly half. N.hempishere teams like to do phases in the 22 but it's not possible to do this.
When break tackles it feels like players lose momentum and makes it easy for them to be caught
Slowing down the overall speed of players so it doesn't seem like it's full pace all of the time
Referee sounds like hes in a box rather than on a field. I think this needs completely overhauling!
Changes in Ref outfits would be nice for either differing competitions or teams so they do not seem like another player.
The passing flow would be nice to have it more seamless rsth than players catching the ball at odd angles.
The haka.. does it always include all players including the bench? Seems alot of people
TMO too look more at the grounding than at the play up to the grounding.
Lastly have the rucks look less like static mauls and more like people at differing angles.
Hopefully some of these things will be adapted.. there are loads of changes to make it perfect but I think it has a very good base to get there. Regardless of early release or not. This is a start, i hope to see constant updates and constant changes to increase performance, gameplay and entertainment
