For everyone that pre-orderded the game wether its on pc, xbox or ps and is denied access should be compensated for it.
If I hear that people who didn't pre-ordered got access because ubisoft was giving away codes and who did are being denied because a limit has been reached then thats just unfair. Also saying that you at ubisoft didn't expect so many players to respond seems highly unlikely.
This is in my opinion something you could expect if its such a hype and therefore handing out guaranteed access with pre-ordering is just a big mistake from ubisoft side.
Wich only makes it fair if the players who's access got denied even though they pre-ordered the game should be compensated for it.
Wether with extended beta time or with some ingame stuff on the release.
