What are people’s prediction for next league mechanic?

I hope it's delve. I think there needs to be some consistently scaling content to push builds.

I'd rather they just focus on the endgame loop itself and then maybe flesh out/rework some of the existing mechanics. Don't need anything new for now. I don't think it's a good idea for them to focus on new content when they need to nail the endgame rework.

Keepers got a pretty middling reception in POE1, I'd be skeptical it comes to 2 as-is since movement is a lot slower there. We know for sure there are at least a few more breach bosses coming to 2 at some point, they've said so in interviews

Can we get something new that wasn’t in poe1???

I just want my orb of scouring.

Well if its like the previous 2 it will be re-imagined

Trial of the Ancestor's would be cool to bring back.

Blight would be neat too

Personally, I'd like to see a version of Betrayal.

Hopefully delve

Whatever it is it's going to be buggy and exploitable :D
