The marioing isn't the problem
The issue is
>shitty laggy online
>shitty hardware
>does not communicate with their fanbase or indicate that they are listening
>region locking, the most arbitrary flaw
>dlc hidden behind amiibo which are expensive and hard to find
>a lack of third party support means that Nintendo cannot afford to make bad games. If they publish 6 Wii U games a year and two are mediocre, then that's only 4 good games in that year. See: Federation Force, Paper Mario Shitter Star 2.0, #FE (actually this might be alright) and a heap of shovel ware f2p shit
>they flip flopped between casuals and 'hardcore' gamers. You can get one or the other, but not both Nintendo
>Bowing to soccer mums and removing lewd content because westerners are faggy puritans. Also shitty dubs. #FE thankfully isn't being dubbed at all, and is just in it's original Japanese audio
