Bossing-only as a Playstyle is Not Viable

I went into this game as an osrs player hoping that bossing would be a viable money making method as bossing is way more interesting to me than just killing screens of trash mobs over and over.
But map bosses are just a means to get juiced waystones to juice killing league mechanic trash mobs over and over, not to make money from the boss itself, and the main pinnacle boss of the game is a casino where unless you hit the jackpot you are just losing money, maybe I'm unlucky idk. (turned 20d to 10d farming t3 arbiter)
Xesht is profitable in the long run, but half of a breachstone is killing trash mobs where you are also dps checked, so your build can't be single target boss focused.
Simulacrum has some interesting bosses, but is mostly killing waves of trash mobs. You're not even guaranteed a boss for logbooks.
Was poe1 also like this? If I like bossing and farming bosses should I just not play this game?
