I wonder how big chance these regular codes will give you to enter the closed beta.
The chance is probably not big
If you see for example the keys from Curse, which were if I recall 50.000?
Everyone is gonna have one of those, so it pretty much cancells out the increase of chance that you'll be picked since everyone has one of them. Same of the other ones.
Only the truly lazy people will have less chance, since they dont even bother to get the normal beta invites.
