Hey everyone! Riot Reinboom here with context on an upcoming change to pathfinding.
The short of it: We're rewriting a lot of the "stuck pathing" rules the game has in order to make the system more predictable and, when 'stuck', more forgiving. Ideally, helping alleviate a lot of the creep blocking pains.
This change will be on the PBE but will not be going out with next patch. Changing anything with pathfinding could have some serious feels unknowns that we would like to capture and understand first.
There are three major areas this change should touch.
1. What happens when a unit is actively on top of and sticking with another unit. If you've seen someone get stuck by Krugs or a ward this is a major part of it. The new rules should detect for overlaps better and let the champion walk away freely from their overlaps (effectively, a pseuo-ghost effect if you're directly on top of something).
2. How units path between packs of units, like a large minion wave. The goal here is to make this more predictable. It should be more obvious why your champion may try to move through a group of minions or why they won't try.
3. How units predict where they can go towards. For pathing, there's some amount of look-ahead needed in order to make sure a unit isn't moving towards an area they will soon be stuck in. Ideally, your character (and minions!) should be avoiding areas that will soon block them more so than on live.
We're extra interested in any reports where you get stuck by a single unit anywhere on the map. Screenshots and videos super super useful if you do find any.
Any feedback about last hitting as a melee champion is also highly encouraged. :)
