Looks like WWE 2K18’s latest patch on Nintendo Switch has increased loading times rather than reducing it.
According to ContraNetwork, it previously took 5 minutes and 12 seconds to load the game (Loading -> John Cena enters -> Undertaker 91 enters). After the patch is installed, the time taken for the game to load has increased to 5 minutes and 16 seconds.
