Auto-Aim Question

I recently came back to ROTMG after a pretty long hiatus and for awhile everyone was using the auto-aim version that would shoot at invulnerable things and was wondering why it switched back so it wouldn't.

I found that it worked a lot better, especially for characters with low dex/ASS to have it keep shooting than starting up late because something becomes vulnerable again. Also, it was a lot less obvious you were hacking.

Was there a reason for the switchback? Just curious.

My assumption is most people just change the lines in the coding and not actually bother removing that check itself.
