For anyone playing mixed games, whether be H.O.R.S.E., 8 to 12 game-mixes, dealer’s choice, etc., why should anyone get into learning how to play different poker formats aside from the popular ones like NLHE and PLO? What has experience in mixed games done for your overall poker game?

I’m curious as to what learning mixed games can do for my own poker game. I mainly play NLHE cash, so I am curious if there are concepts or ideas from playing Stud, 2-7 Single Draw, Omaha 8/B, etc. that can help with my current game. Or better yet, why learn how to play games that are not as prevalent as NLHE and PLO? I know there are mixed game tournaments as well as a few tournaments for one type of poker; although they are rarer than NLHE MTTs. I have been considering learning PLO just in case there’s a good Vegas or CA game to capitalize on.
