I’ve stabilised at ~170 (on my ‘main’ account), but I’m still running into people who are still using naive_navigate. I don’t know if that’s classed as high rank, but it’s definitely not middle to low.
For reference, this is the kind of match I was talking about:
Our bots at the time had roughly similar scores (~56), so I would have expected a close game, however it was clutched almost immediately because they were running naive navigate. This happened at ~240 (not high ranks, but not low) so it’s still a fairly common thing even approaching gold league.
For the record, I’ve stopped using the strategy because I felt far too scummy running it : P
