Is Serpent Strike bugged?
That could be caused because you have selected other enemy than the one you want to hit.
The auto target is being behaving funny this last days, is better if you use the “choose the closest target” or pick it up manually.
last couple weeks ive been having weird skill lag for the first time in gw2. Also there are a lot of complaints lately about many skills that causes movement not behaving correctly/reliably. Off the top of my head warrior GS skill Rush misses ALOT. But that skill has always been “moody”.
If you read the details of how it calculates the attack you might better understand why it acts this way.

I had similar problems with “phantom” off hand ax throws until I hid my backpiece.
so theres no way you can predict whether it’ll hit or not? nice skill anet I’m impressed
