It's not an odd game to me. When NLHE become more popular towards the end of the 20th century, standard poker was generally 5c draw, where you get to make live reads on every single face card that comes up. You could do very well out of poker with little strategic understanding of the game, as long as you had good psychological discipline and the ability to read opponents. Those guys would have found NLHE to be like muting an entire sense and fumbling around in the dark.
I've described PLO before as like treading water in the bits inbetween where you cooler the f**k out of your opponents. When you're getting coolered yourself and bad beat in the most improbably ways, pot after pot for thousands of hands, losing 35 out of every 40 flips, getting no action on your big hands, etc etc, which happen far more in PLO than in NLHE, it's easy to feel like you're drowning. But if you can stay alive i.e. keep playing well enough to have your head above water then when your luck turns and you're the one doing the coolering, you'll make your money back and then some.
