Ego move, probably not, possibly something that can be understood with a Myers-Briggs. Someone changes a line, and someone else gets upset and changes it back-has happened a lot in the past and result can be line wars. I would just be highly attentive because based on philosophies etc, things change a lot. My favorite is the permanent versus temporary line arrows, and the temporary line arrows point in the direction of my travel ,even though they contradict the existing line arrows.

Why would someone point arrows in the direction they travel? Contraindicated from what is taught in class. That is scary to me

Don't know. I read this frequently on Scubaboard's cave diving subforum. Usually the comment is prefaced by, "I was taught" or "My instructor taught me". There is some argument that there are permanent line arrows and personal line arrows that people have marked in some way. The rationale that a personal line arrow can contradict a permanent line arrow, especially if an exit up ahead hasn't been verified. My thoughts, in a lights out, or zero viz situation, especially when you are stressed, nobody will tell the difference between permanent and personal line arrows. Conventional wisdom is that all line arrows should be consistent, and use nondirectional markers for something different.

We had this happen on a recent dive in Peacock a month or so ago. We entered P1 planning to do the wishbone circuit. At some point we came across an arrow facing the opposite direction and didn't think much of it. Then the arrow, shortly after, switched back to the original, exiting direction. This was a bit confusing but the whole team noticed and confirmed the arrow changes. Later on we were hanging out at Dive Outpost and asked DJ and he said sometimes you find this. It was not a big deal since we all noticed it but I could see this causing confusion if it were missed or even worse finding this in zero visibility. I don't understand the logic behind doing this at all.
