Reintroducing my PRs that were lost in the wallening revert. (#86439)

## About The Pull Request
This PR reintroduces #85759, #85892 and #85894.
#85892 has post-wallening arrows, but it isn't a big deal because they
fit the top-down or 3/4 style we've for a lot of things.

## Why It's Good For The Game
Reintroducing lost features and improvements. Remember to remove the
'Lost in the wallening revert' label from those PRs when this is merged.
