Yeah, for me the issue isn't the small oscillation while moving in a straight line, I actually like that feature as it's more realistic imo. For me the problem is the oscillation coming out of a turn. It really does make torpedo dodging, and positioning your ships in knife fights incredibly challenging.
Also, idk if anyone else has had this issue, but the avoid ships button is completely broken for me for light cruisers and I believe other classes as well. They'll just ram stuff when in formations and sink.
Edit: Nick, I understand the frustration from your end on our negativity. We are all here commenting, advising, and playing the game because we enjoy it. I think people are just frustrated by your phrasing this as having a minimal impact on gameplay.
