A suggestion to improve login screens in many events.
An option to select a certain login screen from whatever selection is present due to the time of any certain event would be convenient to you and the players. It would promote whatever you just released and the event that coincidentally is happening along with the new releases will be compensated by the players having the choice to select their login screens whether it be ( for example ) the reworked akali, pool party event, or the original login screen that automatically places itself after a patch when the new login screens barely made enough presence in the client.
To sum things up, riot will be able to easily promote multiple assets at once by having given us the option to swap between'em just like (SG UDYR) or ( DJ SONA )
EDIT: Just to clear the misunderstanding, I'm not suggesting riot to enable the entire roster login screens. All I'm saying is to give us the option to swap or pick any "RECENT" OR "LATEST" login screens that riot struggles to show off such as the pp event along with the akali rework or the aatrox rework or the cho gath skin that barely had any screen time. It just feels a waste to neglect any of the recent login screens. So my suggestion is to give us the option to choose between the limited recent login screens and we can just swap between'em.
