Hollow Palm has been very fun this season but according to Poe.ninja almost no one is running it.

Yes, we're all aware that quarterstaff is stronger, but end game builds with Ice Strike + Hollow Palm are still clearing 1mil DPS easily. It's still not as strong as the meta stuff, but I'm having a blast with it and still destroying all of the endgame content without much of an issue. Aside from a few bugs, it's been some of the most fun I've had playing PoE2.
