Lightning strike desync

I am relatively new to PoE and this is my first SSF League attempt..

I am occasionally having trouble dealing demage to monsters with the Lightning Strike skill.

Most of my damage comes from direct melee hits, not projectiles. Over time I learned to recognize what it looks like when monsters receive damage from the projectiles compared to my melee strikes.

Very often it happens that my character gets teleported back when using movement skill - whirling blades - for example.

It has happened a few times now where I was smacking the s* out of a monster and it would just not receive any proper damage, only for me to be suddenly teleported further away from the monster.

I have latency graph on and am playing with 14-15ms without any major spikes.

Not always does my character teleport, but I am quite sure what happens is that 5 out of 10 cases, my character does not deal melee damage because I am not considered to be close enough, even though visually I am.

I have no other explanation as to why would some monsters just not receive most of my damage until I slightly move back and forth.

Like I mentioned, not always does my character teleport - but any instances where I would be standing directly at an enemy and not deal much damage - look and feel exactly the same as the cases where the character would eventually teleport away.

This makes me believe that there is indeed a problem worth reporting.
Please consider it.
