Fall (or impact) damage plagues not only builders but explorers too, if not more so.
I have tried with and without, and only makes a TINY difference only at max level. I was still dying in silly places with it almost maxed.
This actually makes it worse…
This does absolutely nothing for explorers.
It is one of the top 3 reasons I am no longer an active player.
So yes. Something definitely needs to change here
